Consider the equilibrium:
C2H6(g)⇌C2H4(g)+H2(g).
At 1000. K and constant total pressure of 1.00 bar, C2H6(g) is introduced into a reaction vessel. The total pressure is held constant at 1 bar and at equilibrium the composition of the mixture in mole percent is H2(g): 26.6 %, C2H4(g): 26.6 %, and C2H6(g): 46.8 %.
Required:
(a) Calculate Kp at 1000 K.
If ΔH of reaction = 137 kJ/mol, calculate the value of Kp at 298.15 K.
(b) Calculate ΔG of reaction for this reaction at 298.15 K.
