1. fa solid floats on its own liquid phase, do you expect the melting temperature increase or decrease with increasing pressure? Please explain why? (10%)

2. Please estimate the enthalpy of solidification for at I atm and - 10℃ (10%)

3. Please find the Gibbs firee energy, enthalpy, and entropy by mixing Ar and H₂ at a ratio of 95:5, assuming all starting gases and the gas mixtures are ideal gases at I atm and 298 K. (20%)

4. For 2 moles of ideal gas that has c_v=2.5 R, please calculate its change of intemal energy, enthalpy, entropy, heat, and work for a straight path in P-V space starting from 1 atm and 273 K to a final pressure and temperature of 10 atm and 373 K. Is the work done on the gas or by the gas? (25%)

5. Please sketch the corresponding phase diagram and△G-X plot for each phase in the reaction at peritectic temperature. Please indicate clearly the curves for each phase, stable phases and their boundaries and regions. (20%)

6. Ifexcess carbon is present in a container that originally has 1:1 of CO and CO₂and no other gases, please explain the change of CO:CO₂ ratio with increasing temperature. (15%)
