Honestly speaking, when I was a child, I liked Marcos than Aquino. I don't know why but I liked the "L" sign of the Marcos better than the Aquino's "V" sign. I also used to argue with my classmates while in grade school on who was the better president—Ferdinand Marcos or Cory Aquino (that time the l...

| 8. | Rates of Reaction Not very good
What affects the rate of reaction? ... Chemical kinetics is the study of reaction rates, it shows that three things that must be right at the molecular level if the reaction is to occur. ... Not all collisions have this energy, but some are more likely to at higher temperatures. ... Though if one...

| 9. | Rates of reaction
...
There are four factors that affect the rate of reaction:
1 - Temperature. ... They will collide more frequently increasing the rate of reaction. ...
Catalyst:
Addition of a catalyst increases the rate of reaction as it reduces the activation energy of the reactants. The catalyst ...

| 10. | HOW DOES CONCENTRATION OF ACID AFFECT THE RATE OF REACTION
Aim: To carry out an investigation on whether the rate of reaction changes when different concentrations of acid are combined with sodium thiosulphate.
Prediction: I believe that by diluting the hydrochloric acid (decreasing the concentration), the rate of reaction would take place slower each ti...

| 19. | Experiment to study the Effect of a catalyst on the rate of reaction
Hypothesis
The Collision Theory says that the role of a catalyst is to provide the reaction with an extra, alternative pathway for the reaction to occur; the activation energy for this alternative pathway is less than the activation energy for the reaction without the catalyst. As a result, more ...

| 20. | Rate of Reaction
Introduction
The rate of a reaction is the speed at which reactants are converted into products. Experiments show that for most reactions, the concentrations of all participants change the most rapidly at the beginning of the reaction. That is, the concentration of the products shows the greatest...
