We are being asked to calculate Kp for the given reaction:
2 NO(g) + O2(g) ⇌ 2 NO2(g)
When dealing with equilibrium and Kp:
• Kp → equilibrium units in terms of pressure
• Kp is an equilibrium expression:
▪ only gaseous species are included in the equilibrium expression
▪ the coefficient of each compound in the reaction equation will be the exponent of the pressures in the equilibrium expression
Consider the following reaction: 2NO(g) + O 2(g) ⇌ 2NO2(g)
A reaction mixture at 175 K initially contains 522 torr of NO and 421 torr of O2. At equilibrium, the total pressure in the reaction mixture is 748 torr. Calculate Kp at this temperature.
