Question

If the concentration of the reactants in a chemical reaction is increased, the rate of the

reaction usually
a. decreases.
B. increases.
C. remains the same.

Answer 1

B. increases.

Step-by-step explanation:

When the concentration of the reactants in a chemical reaction is increased, the rate of the reaction usually increases. This is because increasing the concentration of the reactants increases the number of collisions between reactant molecules, which increases the likelihood of a successful collision that leads to a reaction. This is known as the collision theory of chemical reactions.
