In the reaction of formation of sulphur trioxide by contact process $2SO_2 + O_2 \rightleftharpoons 2SO_3$,the rate of reaction was measured as $\frac{d[O_2]}{dt} = -2.5 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$. The rate of reaction in terms of $[SO_2]$ in $mol \ L^{-1} \ s^{-1}$ will be:

  • A
    $-1.25 \times 10^{-4}$
  • B
    $-2.50 \times 10^{-4}$
  • C
    $-3.75 \times 10^{-4}$
  • D
    $-5.00 \times 10^{-4}$
