**Problem 57: Evaluation of Reaction Spontaneity at 25°C**For each of the following reactions, calculate the changes in enthalpy (\(\Delta H^\circ_{\text{rxn}}\)), entropy (\(\Delta S^\circ_{\text{rxn}}\)), and Gibbs free energy (\(\Delta G^\circ_{\text{rxn}}\)) at 25°C. Determine whether each reaction is spontaneous under these conditions. If a reaction is not spontaneous, assess whether a change in temperature could make it spontaneous. Indicate if the temperature should be increased or decreased from 25°C to achieve spontaneity.**Reactions:**a. \( \text{N}_2\text{O}_4(g) \rightarrow 2 \text{NO}_2(g) \)b. \( \text{NH}_4\text{Cl}(s) \rightarrow \text{HCl}(g) + \text{NH}_3(g) \)c. \( 3 \text{H}_2(g) + \text{Fe}_2\text{O}_3(s) \rightarrow 2 \text{Fe}(s) + 3 \text{H}_2\text{O}(g) \) d. \( \text{N}_2(g) + 3 \text{H}_2(g) \rightarrow 2 \text{NH}_3(g) \)
