Question

Which of the statements below is not a correct part of collision theory?

a. Reactant molecules must have some minimum amount of energy to react.
b. Every time reactant molecules collide, a reaction occurs.
c. The orientation of reactant molecules has an effect on the outcome of the reaction.

Answer 1

b. Every time reactant molecules collide, a reaction occurs.

Step-by-step explanation:

Each gas molecule undergoes about 10¹⁰ collisions per second. If a reaction occurred every time there was a collision, the reaction would be finished almost instantaneously.

a. and c. are wrong. They are parts of collision theory.
