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
Relationship between thickness of intermetallic and annealing conditions: (a) annealing temperature  Fig.4 shows the relationship between thicknesses of intermetalic and annealing condition. The temperature increases intermetalic thickness also increases. The intermetalic layer thickness with various times and temperature was analyzed. Annealing time increases intermetalic thickness also increases . Fig 5.
It will cause more oxygen to be produced thus result in the increase of the final volume of foam in each measuring cylinder than actual value. The rate of reaction of enzyme will then higher than expected. One possible solution for this error is changing the ruler into another measurement instrument such
Conclusion Observing the graph above, I can conclude that the higher the concentration of hydrochloric acid (in molars) the faster the rate of reaction it has with calcium carbonate. I can see this because on my graph the higher the concentration the higher the line goes on the graph. An example, 1.0 molar concentration is above 0.5 molar but it is below 2.0 molar at the 60-second line. Therefore it has a faster rate of reaction then 0.5 molar but a slower rate of reaction that 1.5 molar. The results were what I expected although some anomalies did occur and are highlighted (outliers) in the tables and on graphs, however these did not affect any of the results and were probably only misreading as there were never more than one for the same
Diffusion describes the tendency of molecules to move from an area of high concentration to an area of low concentration. This is also known as moving down their concentration gradient. The particles in a solution are constantly in motion as a result of their kinetic energy. This causes collisions, which in turn causes the particles to ricochet off of one another and switch direction. Since the particles are in an area of high concentration, there is a greater likelihood of more collisions occurring, resulting in the particles being propelled in the opposite direction, or towards the area of low concentration, eventually leading to a sense of equilibrium of the particles on each side of the gradient.
From the fig it is observed that with an increase in voltage there is increase in spark energy and as a result MRR increases.The same pattern is observed for electrolytic concentration which is due to continuous ionization and deionization at a faster rate which results in increase in thermal energy. But if we focus on inter-electrode gap, the same pattern is not observed i.e. MRR decreases with increase in inter-electrode gap and finally S/N ratio also decreases. Figure 3: Main Effect Plot for S/N ratios 2. Interval Plot of MRR vs other three parameters: Interval plot of MRR vs other factors is plotted to know the most effective range of each parameter.
Another method is to increase the surface area of the solute. Because reactions only occur with the outside molecules, increasing the surface area will in turn increase the number of reactions. The final way is to increase the temperature of the solution. When the temperature of solution is increased, the average kinetic energy of the particles is increased (the particles have different energies). We can observe the way temperature affects rates of reaction in the Maxwell-Boltzmann
With increasing Rhodium molar percentage, the amorphous phase increases in the oxide coating, so it is expected that the capacitance of the three-component coatings is much higher than that of the coatings without Rhodium. At 1.51 V, the two-component coating exhibits a higher capacitance than the triple coatings. This is due to the fact that, in higher over voltages, the released gases will fill the coating’s groove regions and reduce the active surface area of the coating. Therefore, the ability to perform electrochemical reactions will be greatly reduced in high over voltages by increasing the rhodium content. This leads to creation of more cracks in triple coatings and filling of these cracks by released gases which reduces the ability of coatings to perform electrochemical reactions.
Water hammer is a sudden increase in the pressure of a liquid due to an instantaneous conversion of momentum to pressure. A pressure surge or wave caused by the kinetic energy of a fluid in motion when it is caused to stop or change direction suddenly. The movement of liquid mass in a pipe is kinetic energy, which is proportional to the mass of liquid times the square of the velocity . The noises are caused by a very fast moving pressure wave in a closed conduit, usually resulting from a sudden stoppage/block or change in the masses velocity. In any system where change in momentum of the fluid occurs water hammering will be experienced, the larger the mass of the fluid the greater the resultant force.
