Question

What does the rate law tell you about a reaction?

A. How the concentration of the reactants affects the rate of a
reaction
B. How temperature affects the rate of a reaction
C. How the equilibrium constant is related to the rate of a reaction
D. How the rate of a reaction affects the total time of a reaction

Answer 1

A. How the concentration of the reactants affects the rate of a reaction

Step-by-step explanation:

Let's consider a generic reaction.

A + B ⇒ Products

The generic rate law is:

rate = k × [A]ᵃ × [B]ᵇ

where,

• rate: rate of the reaction

• [A] and [B]: molar concentrations of the reactants

• k: rate constant

• a and b: reaction orders

As we can see, the rate law shows how the concentration of the reactants affects the rate of a reaction.
