Question

Choose all of the correct statements concerning collision theory...

Options:
A. Reaction rate depends on reactant concentration
B. Effective collisions lead to product formation
C. Temperature has no effect on reaction rate
D. Catalysts decrease the number of collisions

Answer 1

Collision theory explains how reactant concentration, temperature, and catalysts influence the rate of a chemical reaction.

Step-by-step explanation:

Collision theory explains that the rate of a chemical reaction depends on reactant concentration and the occurrence of effective collisions. Increasing the concentration of reactants increases the frequency of collisions, leading to a faster reaction rate. Temperature also affects reaction rate by increasing the energy available for collisions. A higher temperature results in more collisions and a faster reaction rate. Catalysts, on the other hand, decrease the activation energy required for a successful collision, increasing the number of effective collisions and the reaction rate.
