Question

The equilibrium constant for the reaction SO_3 ( g ) ⇌ SO_2 ( g )+ 12O_2 ( g ) is K_c=4.9 10^-2. The value of K_c for the reaction given below is 2 SO_2 ( g )+O_2 ( g ) ⇌2 SO_3 ( g ) is :

Accepted Answer

Correct answer: D. (d) K_C^ ' = ( 1 K_C )^2= ( 14.9 10^-2 )^2 K_C^ ' =416.49

$The equilibrium constant for the reaction SO_{3} (g) ⇌ SO_{2} (g) + \frac{1}{2} O_{2} (g) is K_{c} = 4.9 \times 10^{- 2} . The value of K_{c} for the reaction given below is 2 SO_{2} (g) + O_{2} (g) ⇌ 2 SO_{3} (g) is :$
