Disadvantages Of The Haber Process

1028 Words5 Pages

Catalysts are substances that cause the acceleration of a chemical reaction, therefore increasing the rate of a chemical reaction, without itself being affected or undergoing any permanent chemical change. Catalysts increase reaction rate by lowering the amount of activation energy needed, meaning that particles can collide with less energy, this results in more particles successfully and effectively colliding. Catalysts don’t get used up in chemical reactions, and therefore can be used repeatedly. Reactions that occur with the presence of catalysts are named catalytic reactions or catalysis; different reactions require different catalysts. Catalysts are used in a number of industries and are important to them as they aid in reducing costs (World Book Encyclopedia C - Ch, 1997).

The Haber process is one such process that uses catalysts and is used in a number of industries; the process was developed by Fritz Haber, a German chemist, and was demonstrated in 1909. The Haber process is a commercial method of manufacturing ammonia (NH3) from nitrogen (N) and hydrogen (H) using iron (Fe) as a catalyst, under the conditions of optimum temperature and pressure. The balanced equation for the production of ammonia through this process is: N2 + 3H2 = 2NH3. The process …show more content…

These disadvantages include: being incompatible with copper so cannot be used in systems with copper pipes; ammonia is a toxic refrigerant, is flammable and poisonous at certain high concentrations, ammonia is corrosive to the skin, eyes and lungs and so should be handled taking safety precautions, small quantities of ammonia could cause throat irritation, coughing, or even threat to human life after 30 minutes of exposure, but fortunately ammonia can be simply detected through its strong odor, and so leaks and other problems can be resolved before causing any serious harm to human lives (DanFoss Industrial

    A mixture of elements is what is known as compounds. Chemical reactions occur when particles react with each other and atoms in molecules get rearranged. Reactions happen either rapidly or slowly. The speed of a reaction is known as the rate of the reaction. This speed of chemical reaction depends on many factors such as temperature, particle size of reactants, and the intensity of reactants.

The experiments were conducted online using Late Nite Labs. Materials: Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer.

    Some factors that influence the speed of a chemical reaction are: (1) surface area of starting reactants; (2) concentration of reactants; (3) temperatures. The particle theory states that a solute dissolved takes place at the surface of the solvent and the larger the surface area of the particle the longer it will take to dissolve. The smaller the area the faster it will

    The first con of net neutrality is that it will prevent competition in the free market. If the internet is regulated by the government that will stifle the free market because if every company if forced to compete on a level playing then the best business won’t be able to rise to the cream of the crop through natural competition. If one ISP raises their prices then that person can just switch over to the company with cheaper rates. A free market is healthy not only for businesses but for the overall economy as well because it will force other companies to have step their game up in order

    Enzymes are proteins that significantly speed up the rate of chemical reactions that take place within cells. Some enzymes help to break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are selective catalysts, meaning that each enzyme only speeds up a specific reaction. The molecules that an enzyme works with are called substrates.

    One of the disadvantages was wasted resources. If there was anything with the product design, or the assembly line, that meant every item in the entire production cycle was effected. When this happened, the manufacturer would often have to get rid of all f these items, attempt to fix the issue, and start over. This led to a lot of wasted product, which was an even bigger problem when resources were limited to begin with. Alon with concern of wasted resources due to manufacturing discrepencies, there was no assurance that the products would sell even if they were all made correctly.

The only gaseous wastes generated by the reaction in the experiment are carbon dioxide and water, which are benign (Lab 3). The decomposition reaction of NaHCO3, generates virtually no waste, therefore less hazardous chemical syntheses. The byproducts of the reaction are gaseous CO2 and H2O which possess little or no toxicity to human health and the environment, because of the amounts released in this experiment. (Lab 3).

Typically, the middle class and upper class use a parenting method Annette Lareau calls “concerted cultivation,” meaning that parents foster children’s talents and interests. Most parents that use this style of rearing follow similar routines such as maneuvering their schedules to alote multiple extracurricular activities, emphasizing the use of vocabulary and reasoning skills, and socializing their children to be comfortable around adults. While these practices seem to be successful in creating and maintaining class reproduction, they

    Reactions in the human body produce hydrogen peroxide as a product (1). Since hydrogen peroxide is poisonous to the human body, catalase catalyzes hydrogen peroxide into water and oxygen (2 H2O2 → 2 H2O + O2) (1). According to the collision theory, a reaction can only occur if particles collide with sufficient energy to overcome the activation energy and with correct geometrical orientation (3). Increasing temperature increases the kinetic energy of the particles which means that an increase in temperature will increase the speed of the hydrogen peroxide and the catalase molecules which
