Question
For the following three reactions a, b and c, equilibrium constants are given
a. CO (g) + H2O (g) ⇌ CO2 (g)+ H2 (g); K1
b. CH4(g) + H2O (g) ⇌ CO (g) + 3H2 (g); K2
c. CH4(g) + 2H2O (g) ⇌ CO2 (g) + 4H2 (g); K2
Which of the following relations is correct?
-
K1√K2 = K3
-
K2K3 = K1
-
K3 = K1K2
-
K3.K32 = K12
Solution
C.
K3 = K1K2
Equation (c) = equation (a) + equation (b) Thus K3 = K1.K2
