General Chemistry 普通化學丙 Quiz 2 12/29 (50 points)
1.Why surrounding receiving heat or offering energy can be regarded as a
reversible process? (5)
2.Briefly describe three laws of thermodynamics. (15)
3.Prove that dH=TdS+VdP, where H is enthalpy, E is internal energy, V and P are
volume and pressure of gas, respectively. (10)
4.At 1500K the process
I2(g, 10atm) → 2I(g, 10atm)
is not spontaneous, However, the process
I2(g, 0.1atm) → 2I(g, 0.1atm)
is spontaneous at 1500K. Explain. (10)
5.Benzene has a melting point of 5.5°C and an enthalpy of fusion of 10.04
kJ/mol at 25°C. The molar heat capacities at constant pressure for solid and
liquid benzene are 100.4 J/K-mol and 133 J/K-mol, respectively.
For the reaction
C6H6(l) ⇋ C6H6(s)
calculate ΔS_sys and ΔS_surr at 10°C. (10)
