Question 4 The reaction enthalpy and entropy of the gas phase reaction, CH,(9)+H(9)2CH(9) are AH° =-137.0 kJ mol“ and AS° =-120.5 ) mol-'K' at 298 K. In the temperature range 298 - 1000 K, the difference in molar heat capacities of products and reactants (at constant pressure) is: AC, /JK' mol'=-27.2+0.0256(T/K). 1.0 mol of C2H4 (9) and 1.0 mol of H2(g) are mixed at a fixed total pressure and 1000 K What is the value of the total pressure that would be needed for the mole fraction of ethane at equilibrium to be 0.99 at 1000 K?
