Question

For the following reactions, equilibrium constants are given

CO(g) + H2O(g) 
 CO2(g) + H2(g) ; K1
CH4(g) + H2O(g) 
 CO(g) + 3H2O(g) ; K2
CH4(g) + 2H2O(g) 
CO2(g) + 4H2(g) ; K3

Find the relation between K1, K2 and
K3

Dear Student,

There
must be a correction in the question that you have
mentioned
In this question if we add reaction 1 and 2,
the new reaction becomes:
CO (g) + H2O (g)
------CO2 (g) +H2 (g) K1
CH4(g) + H2O (g)
--------CO (g) + 3H2 (g) K2
ON ADDING THE ABOVE TWO,
CO (g) + H2O (g) +
CH4(g) + H2O (g)------------CO (g) +
3H2 + CO2 (g)
+H2
The K3 value will be (K1)*K2
CO (g) + CH4(g) +2
H2O(g) ------------- CO2 (g) +4 H2
thus K3 = K1*K2
