Question

The equilibrium constants for the reactions X = 2Y and Z = P + Q are $K_{1}and{K}_2$, respectively. If the initial concentrations and the degree of dissociation of X and Z are the same, the ratio $\frac{K_1}{K_2}$ is.

• A. 4
• B. 1
• C. 0.5
• D. 2

Answer 1

The correct option is A

4

$X\rightleftharpoons 2YZ\rightleftharpoons P+Qa-a\alpha 2a\alpha a-a\alpha a\alpha a\alpha k_1\frac{4a^2{\alpha }^2}{a(1-\alpha )}{k}_2\frac{a^2{\alpha }^2}{a(1-\alpha )}\frac{k_1}{k_2}=4$
