Solution:

Concept:

Rate of reaction measures how fast a reactant concentration changes over time.

Explanation:

The rate of a chemical reaction is defined as the change in concentration of a reactant or product per unit time:

\text{Rate} = -\frac{\Delta[\text{Reactant}]}{\Delta t}

Thus, the change in concentration of a reactant with time is the rate of reaction.
