Question

For an elementary chemical reaction, A2 xrightleftharpoons[k-1] k12A , the expression for (d[A]/dt) is : (A) 2k1[A2] - k-1 [A]2 (B) k1[A2] - k-1 [A]2 (C) 2k1[A2] - 2k-1 [A]2 (D) k1[A2] + k-1 [A]2

A2 xrightleftharpoons[K-1]K1 2A (d[A]/dt) =2k1 [A2]- 2k-1[A]2

Q. For an elementary chemical reaction, $A_{2} k_{1} k_{- 1} 2 A$ , the expression for $\frac{d [ A ]}{d t}$ is :

$2 k_{1} [A_{2}] - k_{- 1} [A]^{2}$

$k_{1} [A_{2}] - k_{- 1} [A]^{2}$

$2 k_{1} [A_{2}] - 2 k_{- 1} [A]^{2}$

$k_{1} [A_{2}] + k_{- 1} [A]^{2}$

$A_{2} K_{1} K_{- 1} 2 A$
$\frac{d [ A ]}{d t} = 2 k_{1} [A_{2}] - 2 k_{- 1} [A]^{2}$

Q. For an elementary chemical reaction, A2​k1​k−1​​2A , the expression for dtd[A]​ is :

2k1​[A2​]−k−1​[A]2

k1​[A2​]−k−1​[A]2

2k1​[A2​]−2k−1​[A]2

k1​[A2​]+k−1​[A]2
