and

O_{2}

are expressed as

\frac{d [N O]}{d t}

and

\frac{d [N O_{2}]}{d t}

Solution

The correct option is C The decrease in $[N O_{2}]$ and the increase in [ $O_{2}$ ] proceed at the same rate
The rate of reaction in terms of products and reactants:

Rate $= - \frac{1}{2} \frac{d [N O_{2}]}{d t} = + \frac{1}{2} \frac{d [N O]}{d t} = + \frac{d [O_{2}]}{d t}$

So, decrease in $[N O_{2}]$ is twice the increase in $[O_{2}]$ . So, it does not proceed at same rate.

For the reaction, 2NO2→2NO+O2 which of the following is false?

The correct option is C The decrease in [NO2] and the increase in [O2] proceed at the same rateThe rate of reaction in terms of products and reactants:Rate=−12d[NO2]dt=+12d[NO]dt=+d[O2]dtSo, decrease in [NO2] is twice the increase in [O2]. So, it does not proceed at same rate.
