Unformatted text preview: following expressions is a correct representation of dG? a) dG = VdP + S dT b) dG = VdP - S dT c) dG = - PdV + S dT d) dG = - PdV - S dT e) dG = VdP + T dS f) dG = VdP - T dS g) dG = - PdV + T dS h) dG = - PdV - T dS Show the derivation leading to your choice. Question 3: (5 points) Mathematically speaking, what are we saying when we state that a process is not spontaneous under conditions of constant volume and constant temperature? a) ΔG < 0 b) ΔG ≤ 0 c) ΔG ≥ 0 d) ΔG > 0 e) ΔA < 0 f) ΔA ≤ 0 f) ΔA ≥ 0 g) ΔA > 0 Explain your reasoning. Question 4: (5 points) For an ideal gas, the expression dG – dA can be written as: a) + nR dT b) – pdV c) + Vdp d) + TdS e) – nRdT f) + pdV g) – Vdp h) – TdS i) – SdT j) + SdT Show how you arrive at the chosen result. 1 Question 5: (5 points) Consider the following chemical...
