Question

Why don't all collisions between reactant molecules lead to a chemical reaction?


A. Collisions between reactants always result in a chemical reaction.


B. Collisions of reactants are not required for chemical reactions to occur. Reactant chemicals are attraction to one another through intermolecular forces.


C. Most collisions have a lower energy level than the activation energy required for a chemical reaction to occur and the reactants do not always have the correct orientation.


D. Chemical reactions occur randomly.

Answer 1

C. Most collisions have a lower energy level than the activation energy required for a chemical reaction to occur and the reactants do not always have the correct orientation.
