Vedclass · Answer

(B) For a general reaction $aA + bB ightarrow cC + dD$,the average rate of reaction is given by: $	ext{Rate} = -\frac{1}{a} \frac{\Delta[A]}{\Delta t} = -\frac{1}{b} \frac{\Delta[B]}{\Delta t} = \frac{1}{c} \frac{\Delta[C]}{\Delta t} = \frac{1}{d} \frac{\Delta[D]}{\Delta t}$.For the reaction $2SO_{2(g)} + O_{2(g)} ightarrow 2SO_{3(g)}$,the rate expression is: $	ext{Rate} = -\frac{1}{2} \frac{\Delta[SO_2]}{\Delta t} = -\frac{\Delta[O_2]}{\Delta t} = \frac{1}{2} \frac{\Delta[SO_3]}{\Delta t}$.Comparing this with the given options,$-\frac{\Delta[O_2]}{\Delta t}$ is a correct representation of the average rate of reaction.

The average rate of reaction $2SO_{2(g)} + O_{2(g)} \rightarrow 2SO_{3(g)}$ is written as
