Consider the gaseous reaction CO(g)+ Cl₂(g) COCl₂(g).What is the expression for K_p in terms of K?

Question

Quizplus · Accepted Answer

The expression for the equilibrium constant for a gaseous reaction is given by: 
Kp = Kc(RT)^Δn 
where:
Kp = equilibrium constant in terms of partial pressures
Kc = equilibrium constant in terms of concentrations
R = gas constant
T = temperature
Δn = difference in the number of moles of gaseous products and reactants

In the given reaction, Δn = 1 - 1 = 0, because the number of moles of gaseous products and reactants is the same. Therefore, the expression for Kp in terms of K is:
Kp = K(RT)^0 = K/1 = K/RT
