Question

For the reaction, $A+B\rightleftharpoons C$, the rate constants for the forward and the reverse reactions are $4\times {10}^2$ and $2\times {10}^2$ respectively.

The value of equilibrium constant K for the reaction would be :

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

Answer: (B)

2

Given the reaction is, A+B⇌C

We know, the equilibrium constant for the reaction is $K=\frac{K_f}{K_b}$

$\therefore K=\frac{4\times {10}^2}{2\times {10}^2}=2$

So, the correct option is $B$
