Question

For the chemical reaction $N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)$ , the correct option is:

1

$-\frac{1}{3} \frac{d[H_2]}{dt} = \frac{1}{2} \frac{d[NH_3]}{dt}$

2

$-\frac{d[N_2]}{dt} = 2 \frac{d[NH_3]}{dt}$

3

$-\frac{d[N_2]}{dt} = \frac{1}{2} \frac{d[NH_3]}{dt}$

4

$3 \frac{d[H_2]}{dt} = 2 \frac{d[NH_3]}{dt}$

Step-by-Step Solution

For the reaction $N_2 + 3H_2 \rightleftharpoons 2NH_3$ , the rate of reaction is given by: $-\frac{d[N_2]}{dt} = -\frac{1}{3} \frac{d[H_2]}{dt} = +\frac{1}{2} \frac{d[NH_3]}{dt}$ . Thus, $-\frac{d[N_2]}{dt} = \frac{1}{2} \frac{d[NH_3]}{dt}$ .
