Question

For reaction, $2A+B\rightleftharpoons 2C,K=x,$ Equilibrium constant for $C\rightleftharpoons A+\frac{1}{2}B$ will be

• A. $x$
• B. $\frac{x}{2}$
• C. $\frac{1}{\sqrt{x}}$
• D. $\sqrt{x}$

Answer 1

The correct option is C

$\frac{1}{\sqrt{x}}$

Given reaction:

$2A+B\rightleftharpoons 2C$ ; $K=x$

$\therefore A+\frac{1}{2}B\rightleftharpoons C$ ; $K=\sqrt{x}$

$\therefore C\rightleftharpoons A+\frac{1}{2}B$ ; $K=\frac{1}{\sqrt{x}}$
