Question

which of the following will increase the rate of a chemical reaction? multiple choice an increase in reactant concentration an increase in product concentration a decreased temperature enzyme inhibition

Explanation:

Increasing reactant concentration provides more particles for collisions, which speeds up the reaction rate. Increasing product concentration usually shifts equilibrium rather than directly increasing reaction rate. Decreasing temperature slows down molecular motion and reaction rate. Enzyme inhibition reduces the catalytic ability of enzymes, thus decreasing the reaction rate.

Answer:

An increase in reactant concentration
