The equilibrium constant for the reaction SO 3 ( g ) ⇌ SO 2 ( g ) + 2 1 O 2 ( g ) is K c = 4.9 × 1 0 − 2 . The value of K c for the reaction given below is 2 SO 2 ( g ) + O 2 ( g ) ⇌ 2

Question

The equilibrium constant for the reaction $SO_{3} (g) ⇌ SO_{2} (g) + \frac{1}{2} O_{2} (g)$ is $K_{c} = 4.9 \times 1 0^{- 2}$ . The value of $K_{c}$ for the reaction given below is $2 SO_{2} (g) + O_{2} (g) ⇌ 2 SO_{3} (g)$ is :

Options:

Answer:

D

Solution:

$K_{C}^{'} = (\frac{1}{K _{C}})^{2} = (\frac{1}{4.9 \times 1 0 ^{- 2}})^{2} K_{C}^{'} = 416.49$
