MHT CET 2022 11th August Evening Shift | Chemical Kinetics Question 38 | Chemistry

$$\frac{1}{3} \frac{\mathrm{d}[\mathrm{x}]}{\mathrm{dt}}=-\frac{1}{2} \frac{\mathrm{d}[\mathrm{y}]}{\mathrm{dt}}=-\frac{\mathrm{d}[\mathrm{Z}]}{\mathrm{dt}}$$,

the reaction can be represented as

$$2 \mathrm{y}+Z \rightarrow 3 \mathrm{x}$$

$$2 \mathrm{y} \rightarrow 3 \mathrm{x}+\mathrm{Z}$$

$$3 x+2 y \rightarrow Z$$

$$3 x \rightarrow 2 y+Z$$

For the reaction $$\mathrm{N}_{2(\mathrm{~g})}+3 \mathrm{H}_{2(\mathrm{~g})} \rightarrow 2 \mathrm{NH}_{3(\mathrm{~g})}$$, what is the relation between $$\frac{\mathrm{d}\left[\mathrm{N}_2\right]}{\mathrm{dt}}$$ and $$\frac{\mathrm{d}\left[\mathrm{H}_2\right]}{\mathrm{dt}}$$ ?

$$3 \frac{\mathrm{d}\left[\mathrm{H}_2\right]}{\mathrm{dt}}=\frac{\mathrm{d}\left[\mathrm{N}_2\right]}{\mathrm{dt}}$$

$$\frac{\mathrm{d}\left[\mathrm{H}_2\right]}{\mathrm{dt}}=3 \frac{\mathrm{d}\left[\mathrm{N}_2\right]}{\mathrm{dt}}$$

$$3 \frac{\mathrm{d}\left[\mathrm{H}_2\right]}{\mathrm{dt}}=2 \frac{\mathrm{d}\left[\mathrm{N}_2\right]}{\mathrm{dt}}$$

$$\frac{\mathrm{d}\left[\mathrm{H}_2\right]}{\mathrm{dt}}=\frac{\mathrm{d}\left[\mathrm{N}_2\right]}{\mathrm{dt}}$$
