Question

What are the characteristics of the first-order reaction?

Answer 1

Hint: A first-order reaction: It is a type of response that depends at a rate that relies directly upon just a single reactant concentration. The unit of first-order reaction constants is ${sec}^{-1}$.

Complete answer:
The characteristics of the first-order reaction are given below;
1. The rate of the reaction is not proportional to the concentration of the reactant.
2. The pace of the reaction is relative to the square of the concentration of the reactant.
3. The rate of the reaction is proportional to the square root of the concentration of the reactant.
4. The pace of reaction is relative to the natural logarithm of the concentration of the reactant.
5. The rate of the reaction is straightforwardly corresponding to the concentration of the reactant.
6. When the concentration of A is increased by 4 times then the rate of the reaction is also increased by 4 times. In general, an increase in the concentration of the reactant by n times increases the rate of the reaction by n times.
7. The time is taken for half the reactant to get reacted, the half-life of the first-order reaction is independent of the concentration. This means that the half-life period of the first-order reaction is constant.

Note:
The possibility to make a mistake is that the rate constant does not depend on the concentration of the reactant while the rate of reaction is directly proportional to the concentration of the reactant.
