78. Solving a chemistry problem

217. Ethan. C2H6 is in the reaction vessel at 1000 K and a total pressure of 1 atm. As a result of the reaction C2H6 (g) \u003d C2H4 (g) + H2 (g), the equilibrium mixture contains 26 mole percent H2, 26 mol. % С2Н4 and 48 mol. % C2H6. 1) Calculate the equilibrium constant Kp at this temperature. 2) Calculate Kp at 298.15 K, assuming the enthalpy of reaction ΔH0 = 137.0 kJ/mol. 3) Calculate ΔG0 at 298.15 K.
