A chemical reaction in which the rate of reaction is directly proportional to the first power of the concentration of the reacting substance is called:

Question

Accepted Answer

Step-by-step explanation:

1. The general rate law for a single reactant A is: $	ext{rate} = k[A]^n$, where $n$ is the order of the reaction.
2. If the rate is directly proportional to the first power of the concentration, then $n=1$ and the rate law becomes $	ext{rate} = k[A]$.
3. A reaction with $n=1$ is defined as a first order reaction.

Therefore the correct choice is the first order reaction.
