Question

At 3000 K the equilibrium partial pressures of CO2, CO and O2 are 0.6, 0.4 and 0.2 bar respectively. The value of ΔGo for the gaseous reaction

2 CO2 ↔ 2 CO + O2

Answer 1

Answer:

+602.67 Kj/mol-1

Explanation:

del G = -RTln(Kp)

         = - .083x3000xln( (.4)^2 x .2 / (.6)^2 )

         =602.67 Kj/mol-1
