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
