Question

For the reaction, $2N_2{O}_5\to 4N{O}_2+O_2$ rate of reaction is

• A. $\frac{1}{2}\frac{d}{dt}\left[N_2{O}_5\right]$
• B. $2\frac{d}{dt}\left[N_2{O}_5\right]$
• C. $4\frac{d}{dt}\left[N{O}_2\right]$
• D. $\frac{1}{4}\frac{d}{dt}\left[N{O}_2\right]$

Answer 1

The correct option is D $\frac{1}{4}\frac{d}{dt}\left[N{O}_2\right]$

The rate of the reaction is $-\frac{1}{2}\frac{d}{dt}\left[N_2{O}_5\right]=\frac{1}{4}\frac{d}{dt}\left[N{O}_2\right]=\frac{d}{dt}\left[O_2\right]$
