Nature of electrolyte: Presence of salts in the electrolyte increases the corrosion rate. v. Presence of impurities in atmosphere: Impurities increase the rate of corrosion. Corrosion is more around industrial areas and sea. This is because of presence of gases in the atmosphere like CO2, H2S, SO2 Control of corrosion Why control
How does temperature affect the rate of reaction of amylase? 3. Hypothesis a. As the temperature increases, the rate of reaction of amylase also increases. After it reaches the optimum temperature, the rate of reaction will start to decrease until all the enzymes are denatured.
Two test tubes were filled with 3ml of 6M HCl respectively. A piece of magnesium ribbon is dropped into one test tube and small pieces of calcium is dropped in the other test tube. The mouth of the test tubes is covered by the thumb once both the magnesium ribbon and small pieces of calcium is dropped into the test
The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate. All enzymes are under the class of protein biomolecule. Amino acids are the basic units that are combined to make up an enzyme.
Here we will be using baking soda and vinegar which are our two components which will cause a chemical reaction. Reactions can be affected by several things such as temperature, concentration and the presence or absence of a catalyst which is a substance which can increase the rate of the reaction. To determine the rate of a reaction there are many methods that can be used. For example. A method which will be used in this experiment will be to use a gas syringe to measure the volume of the gas which has been produced.
Collisions increase or become more violent between molecules at higher temperatures or decrease as the temperature is lowered. 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
Experiment 1 In the first experiment, half a gram of magnesium was combined with 3 milliliters of hydrochloric acid in a glass beaker. The magnesium looked like a gray powder. The hydrochloric acid appeared to be clear liquid and looked very similar to rubbing alcohol. Before, the reaction took place the magnesium and hydrochloric acid weighed 4.44 grams when weighed together. Once the magnesium and the hydrochloric acid were mixed together, the bottom of the beaker felt warm and it started to foam.

It is observed that, as the porosity of the bounding surface increases the velocity also
Change in temperature The reaction rate of enzymes is affected by temperature, as do pH, substrate concentration and enzyme concentration. At low temperature the enzyme activity is low. As the temperature increases the rate of reaction increases,usually 2-fold for every 10 degree Celsius elevate. Effect of Temperature on Enzyme Action. (2018).
