To simulate Natural gas mixture over water, 10 moles of methane (CH4) and 1 mole of ethane (C2H6) were injected into a 30.0 L cylinder at a temperature of 30.0 oC? One third of this cylinder is filled with water so remaining volume is left for the binary gas mixture. Answer the following: (i) Calculate mole fractions Xmethane and Xethane ? Hence calculate the, (a) molar Gibbs free energy-change of mixing ΔGm? (b) molar entropy-change of mixing ΔSm? (ii)With both...
