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); K3
Which of the following relations is correct?
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); K3
Which of the following relations is correct?
Options
A.K1√K2 = K3
B.K2K3 = K1
C.K2 = K1K2
D.K3K13 = K12
Solution
Equation (c) = equation (a) + equation (b)
Thus K3 = K1 . K2
Thus K3 = K1 . K2
