Q.
For the chemical reaction, $N_{2 (g)} + 3 H_{2 (g)} ⇌ 2 {NH}_{3 (g)}$ the correct option is [2019]

1 $3 \frac{d [H_{2}]}{d t} = 2 \frac{d [N H_{3}]}{d t}$

2 $- \frac{1}{3} \frac{d [H_{2}]}{d t} = - \frac{1}{2} \frac{d [N H_{3}]}{d t}$

3 $- \frac{d [N_{2}]}{d t} = 2 \frac{d [N H_{3}]}{d t}$

4 $- \frac{d [N_{2}]}{d t} = \frac{1}{2} \frac{d [N H_{3}]}{d t}$

Ans.
(4)

For the given chemical reaction,

Rate of reaction $= - \frac{d [N_{2}]}{d t} = - \frac{1}{3} \frac{d [H_{2}]}{d t} = \frac{1}{2} \frac{d [{NH}_{3}]}{d t}$

Solution

Q. For the chemical reaction, N2(g)+3H2(g)⇌2NH3(g) the correct option is [2019]

1 3d[H2]dt=2d[NH3]dt

2 -13d[H2]dt=-12d[NH3]dt

3 -d[N2]dt=2d[NH3]dt

4 -d[N2]dt=12d[NH3]dt

Ans. (4) For the given chemical reaction, Rate of reaction =-d[N2]dt=-13d[H2]dt=12d[NH3]dt
