Q11 / 225 · JEE Main 2002 · Chemistry

Units of rate constant of first and zero order reactions in terms of molarity M unit are respectively

  • Correct answer
    A
    $\mathrm{sec}^{-1}, \mathrm{Msec}^{-1}$
  • B
    $\mathrm{sec}^{-1}, \mathrm{M}$
  • C
    Msec $^{-1}, \sec ^{-1}$
  • D
    $\mathrm{M}, \sec ^{-1}$

Solution

$\mathrm{K}=\left(\mathrm{mol} \mathrm{~L}^{-1}\right)^{1-\mathrm{n}} \mathrm{sec}^{-1}, \mathrm{n}=0,1$

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