2. The Gibbs-Helmholtz equation for a chemical reaction is [0 (467/7)] ΔΗ T² where AG is the Gibbs free energy change attending the reaction, AH is the enthalpy change attending the reaction, and T is absolute temperature. Expressing AH in a power series in T, AH = a +bT + cT² where a, b, and c are experimentally determined constants, derive an expression for AG as a function of temperature

At 25 °C, the equilibrium partial pressures for the reaction 3 A(g) + 4B(g) 2 C(g) + 3D(g) were found to be PA = 4.71 atm, PB = 4.26 atm, Pc = 5.75 atm, and P = 4.58 atm. What is the standard change in Gibbs free energy of this reaction at 25 °C? AGrxn = kJ mol
a) Describe in your own words the relationship between standard change in Gibbs free energy associated with a chemical process (∆?o) and an equilibrium constant, Keq. A ∆?o of –3.8 kJ/mol is associated with the equilibrium 2A+B⇌C+D. If A and B are initially present in 1M concentration, find the equilibrium concentrations of all species. You know this reaction to be spontaneous at all temperatures, what can you deduce about the signs of the changes in enthalpy and entropy associated with this process? Why?

Make a non-spontaneous process spontaneous A process that is nonspontaneous can be made spontaneous by coupling it with another process tha is highly spontaneous. The coupling of nonspontaneous reactions with highly spontaneous ones is important in biological system. The oxidization of glucose, for example, is highly spontaneous: C6H12O6(s) + 60₂(g) → 6 CO₂(g) + 6 H₂O(1) Spontaneous reactions such as this ultimately drive the nonspontaneous reactions necessary to sustain life. Can you use Gibbs free energy, enthalpy, and entropy to argue this reaction is highly spontaneous?
