For the reaction AB(g)β‡ŒA(g)+B(g),    ABAB\left( g \right) \rightleftharpoons A\left( g \right) + B\left( g \right),\,\,\,\,AB is 33% dissociated at a total pressure of PP. Therefore, PP is related to KP{K_P} by one of the following options.
View answer and explanation
Correct option: D
P=8KpP = 8{K_p}
Option D (P=8KpP = 8{K_p}) is correct because it is derived from the equilibrium constant expression calculated using the given dissociation percentage.
