At 250°C and 1 bar, phosphorus pentachloride PCl5 partially decomposes to phosphorus trichloride PCl3 and chlorine Cl2: PCl5(g) ⇄ PCl3 (g) + Cl2(g) (1) The standard molar reaction Gibbs free energy for reaction (1) at 250°C is 8.3 kJ mol-1. 1) Calculate the equilibrium constant at 250°C. 2) Calculate the fraction of PCl5 , which has reacted at 250°C and 1 bar, where α is defined as α = substance mass of PCl5 which has reacted / substance amount of PCl5 for the reaction. It must be assumed that all gases behave as ideal gases 3) Let us assume that at the beginning of the reaction we had a mixture where the partial pressure of each of the three gases was 2 bar. In which direction will the reaction proceed?

Question
At 250°C and 1 bar, phosphorus pentachloride PCl5 partially decomposes to phosphorus trichloride PCl3 and chlorine Cl2:
PCl5(g) ⇄ PCl3 (g) + Cl2(g) (1)
The standard molar reaction Gibbs free energy for reaction (1) at 250°C is 8.3 kJ mol-1.
1) Calculate the equilibrium constant at 250°C.
2) Calculate the fraction of PCl5 , which has reacted at 250°C and 1 bar, where α is defined as
α = substance mass of PCl5 which has reacted / substance amount of PCl5 for the reaction.
It must be assumed that all gases behave as ideal gases
3) Let us assume that at the beginning of the reaction we had a mixture where the partial pressure of each of the three gases was 2 bar. In which direction will the reaction proceed?
