For a gaseous reaction, the rate of reaction is expressed in terms of d P d t instead of d C d t or d n d t , where C is concentration and n is the number of moles. Hence, the relation between expressions is

P V = n R T P = n V R T = C R T 1 R T d P d t = 1 V d n d t = d C d t

For a gaseous reaction, the rate of reaction is expressed in terms of $\frac{d P}{d t}$ instead of $\frac{d C}{d t}$ or $\frac{d n}{d t},$ where C is concentration and n is the number of moles. Hence, the relation between expressions is

Options:

Answer:

Solution:

$P V = n R T$
$P = \frac{n}{V} R T = C R T$
$\frac{1}{R T} \frac{d P}{d t} = \frac{1}{V} \frac{d n}{d t} = \frac{d C}{d t}$
