Step 1
In this formula, ΔH is the change in enthalpy (heat content), T is the temperature in Kelvin, and ΔS is the change in entropy (disorder). Given in the problem, we have ΔH = -1279 kJ and ΔS = -364.6 J/K. The temperature is given as 25.0°C. To convert this to Show more…

Calculate the free energy change for this reaction at $25^{\circ} \mathrm{C}$ . Is the reaction spontaneous? (Assume that all reactants and products are in their standard states.) $$\begin{array}{c}{2 \mathrm{Ca}(s)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{CaO}(s)} \\ {\Delta H_{\mathrm{ren}}^{\mathrm{o}}=-1269.8 \mathrm{kJ} ; \Delta S_{\mathrm{rxn}}^{\mathrm{o}}=-364.6 \mathrm{J} / \mathrm{K}}\end{array}$$
