Chemical Kinetics — Easy JEE chemistry MCQ

For a reaction $A \rightarrow B$, the rate doubles when concentration of $A$ is doubled. The order of reaction is:
  1. A. $1$
  2. B. $2$
  3. C. $0$
  4. D. $0.5$

Solution

Rate $\propto [A]^n$ $\frac{r_2}{r_1} = \left(\frac{[A]_2}{[A]_1}\right)^n$ $2 = 2^n \Rightarrow n = 1$
