"Thermite" reactions have been used for welding metal parts such as railway rails and in metal refining. One such thermite reaction is 2 Al(s) + Cr₂O3(s) Al₂O3(s) + 2 Cr(s). During the reaction, the surroundings absorb 536.0 kJ/mol of heat. Is the reaction spontaneous at room temperature (298.15 K) under standard conditions? (See the Standard State Thermodynamic Data table. All values of AS in J/K/mol.) ✔J/K/mol. Therefore, the reaction. First, we compute AS, 40262.1 x 3/K/mol. From this, we compute AS sys univ ✔ spontaneous under the given conditions. - -1758
