Question

Given that the equilibrium constant for the reaction $2 SO_{2} (g) + O_{2} (g) ⇌ 2 SO_{3} (g)$ has a value of 278 at a particular temperature. What is the value of the equilibrium constant for the following reaction at the same temperature? $SO_{3} (g) ⇌ SO_{2} (g) + \frac{1}{2} O_{2} (g)$

Answer:

C

Solution:

$2 SO_{2} + O_{2} ⇌ 2 SO_{3} K = 278 (given) SO_{3} ⇌ SO_{2} + \frac{1}{2} O_{2} K^{'} = (\frac{1}{K}) = \frac{1}{278} = 35.97 \times 1 0^{- 4} = 6 \times 1 0^{- 2}$
