Chemical Engineering Basics

Q1: Consider the equilibrium A(g) + B(g) = AB(g). When the partial pressure of A is 10-2 atm, the partial pressure of B is 10-3 atm and the partial pressure of AB is 1 atm, the equilibrium constant 'K' is

A 10 atm-1

B 105 atm-1

C 10 (dimensionless)

D 105 (dimensionless)

ANS:B - 105 atm-1

Partial pressure = kAB.
1 atm = K(10^-2 atm)(10^-3atm).
k = 10^5 atm^-1.
