Which factor would you change to alter the rate but not the number of effective collisions per second at a fixed concentration?
In collision theory, what two conditions must a collision satisfy to be successful?
Why does increasing temperature both increase the frequency of collisions and the proportion of successful collisions?
Why do many reactions become much faster when a small amount of a catalyst is added?
Why are catalysts described as not being used up during a reaction?
In the context of collision theory, what is the meaning of activation energy?
Which change would increase the rate of a reaction and is most likely to change the activation energy only?
Which classroom safety step is important when carrying out rate experiments that produce gases and why?
How does adding a small amount of impurity that acts as an inhibitor affect a reaction?
Which of the following changes would normally decrease the rate of a reaction?
What effect does a catalyst have on a chemical reaction?
