Q72 / 180 · AIIMS 2010 · Chemistry

For a $1^{\text {st }}$ order reaction if concentration is doubled then rate of reaction becomes

  • Correct answer
    A
    doubles
  • B
    half
  • C
    four times
  • D
    remains same.

Solution

For a first order reaction, rate $=k[A]$, when concentration of $A$ is doubled, the rate becomes double.

Hence, the correct answer is option: 'A'.
