Question
Derive the relation between Kp and Kc.
Solution
Consider a gaseous reaction in a state of equilibrium.
Let PA, PB, Pc and pD be the partial pressures of A, B, C and D respectively at equilibrium, then
and
...(2)
We know that for an ideal gas,
PV = nRT
Substituting the value of partial pressure in equation (1),
[From equation (2)]
