Calculate the change in Gibbs free energy for each of the sets of H rx n ,

Question:

Calculate the change in Gibbs free energy for each of the sets of ΔH_rx_n, ΔS_rxn, and T given in Problem 41. Predict whether or not each reaction is spontaneous at the temperature indicated.

Problem 41

Given the values of ΔH°_rxn, ΔS°_rxn, and T, determine ΔS_univ and predict whether or not each reaction is spontaneous. a. AH n = +115 kJ; ASxn=-263 J/K; T = 298 K b. AH n = -115 kJ; ASn = +263 J/K; T = 298 K c. AH n = -115 kJ;
