In collision theory, what two conditions must a collision satisfy to be successful?
Why does breaking a solid reactant into fine powder increase the reaction rate?
In a student experiment the reaction rate increased when they stirred the mixture. Which is the best explanation?
Which statement describes why increasing concentration speeds up a reaction in solution?
How does light affect the rate of some reactions (e.g., photochemical reactions)?
Which factor would you change to alter the rate but not the number of effective collisions per second at a fixed concentration?
Which of these will NOT normally increase the rate of a reaction?
Why are catalysts described as not being used up during a reaction?
How does adding a small amount of impurity that acts as an inhibitor affect a reaction?
In industrial processes, why might engineers increase pressure and also raise temperature rather than using only one change to increase rate or yield?
Why does increasing temperature both increase the frequency of collisions and the proportion of successful collisions?
