Question

QUESTION 16 The rate of a reaction depends on O collision frequency O collision energy O collision orientation O all of the above O none of the above QUESTION 17 All of the following statements are true EXCEPT chemical reactions involve collisions between the reacting molecules % a three-body collision is less likely than a two-body collision in a series of stepwise reactions, the rate-determining step is the fast one D most collisions between reactant molecules do not lead to product after the addition of catalyst, the collision rate between molecules is stil the same

Explanation / Answer

Question 16. - all of the above

Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation.

Question 17. - In a series of stepwise reaction, the rate determining step is the fast one.

The rate determining step is the slowest step of a chemical reaction that determines the speed (rate) at which the overall reaction proceeds.
