what is the difference between Kp and Kc?
Asked by | 13th Feb, 2012, 01:53: AM
Expert Answer:
Kp is used for reactions involving gases, and the equilibrium constant is expressed in terms of the partial pressures of the gases. Whereas, Kc is used as a general constant, and the concentrations (in moles/liter) are used in calculating its value.
Kc is the ratio of products concentration over reactants concentration and Kp is the ratio of products partial pressures and reactants partial pressures.
Kp = Kc X (R T)^( ?n)
