(e) For each pairing, circle the system (State 1 or State 2) that has the higher entropy (or choose “SAME"). Assume that T and P are the same for each system unless stated otherwise. **NOTE: You must make THREE circles here--this is not a "multiple choice" question.** State 1 State 2 i) 1 mol Na(s) OR 1 mol Li(s) OR SAME ii) 2 mol CH4(g) in 10...

was wondering if someone could help me with some problems on my
test, my teacher allows me to correct them then give them back for
1/2 credit. Along with the correct answer for each I'd like to know
why the answers are wrong and why the new answer is correct. The
questions with a red mark are the incorrect ones.

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...
