Question

For an elementary chemical reaction, $A_2 \underset{k_{-1}}{\stackrel{k_1}{\rightleftharpoons}} 2 A$, the expression for $\frac{d[A]}{d t}$ is :

Select the correct option:

$\mathrm{k}_1\left[\mathrm{~A}_2\right]+\mathrm{k}_{-1}[\mathrm{~A}]^2$

$2 \mathrm{k}_1\left[\mathrm{~A}_2\right]-2 \mathrm{k}_{-1}[\mathrm{~A}]^2$

$2 k_1\left[A_2\right]-k_{-1}[A]^2$

$\mathrm{k}_1\left[\mathrm{~A}_2\right]-\mathrm{k}_{-1}[\mathrm{~A}]^2$

✓ Correct! Well done.
