For the reaction $$2 \mathrm{NO}+\mathrm{Cl}_2 \rightarrow 2 \mathrm{NOCl}$$

What is the relation between $$\frac{\mathrm{d}[\mathrm{NO}]}{\mathrm{dt}}$$ and $$\frac{\mathrm{d}[\mathrm{NOCl}]}{\mathrm{dt}}$$ ?

$$\frac{\mathrm{d}[\mathrm{NO}]}{\mathrm{dt}}=2 \frac{\mathrm{d}[\mathrm{NOCl}]}{\mathrm{dt}}$$

$$\frac{\mathrm{d}[\mathrm{NO}]}{\mathrm{dt}}=\frac{\mathrm{d}[\mathrm{NOCl}]}{\mathrm{dt}}$$

$$\frac{1}{4} \frac{\mathrm{d}[\mathrm{NO}]}{\mathrm{dt}}=\frac{\mathrm{d}[\mathrm{NOCl}]}{\mathrm{dt}}$$

$$4 \frac{\mathrm{d}[\mathrm{NO}]}{\mathrm{dt}}=\frac{\mathrm{d}[\mathrm{NOCl}]}{\mathrm{dt}}$$
