Calculate the Gibbs Energy of reaction at 298 K for the following using 2 methods. First use enthalpies and entropies of formation and DrGo = DrH o - TDrS o to calculate DrG o. Second use DrGo = cDfG o(C) + dDfG o(D) - [aDfG o(A) + bDfG o(B)] and Gibbs energies of formation to find DrGo. Hint: these two values should be nearly identical.
