"Thermite" reactions have been used for welding metal parts such as railway rails and in metal refining. One such thermite reaction is 3 Mg(s) + Cr2O3(s) → 3 MgO(s) + 2 Cr(s). During the reaction, the surroundings absorb 665.1 kJ/mol of heat. Is the reaction spontaneous at room temperature (298.15 K) under standard conditions?
