The reaction is exothermic. This can be determined by calculating the change in enthalpy (ΔH) of the reaction.
ΔH = [2(−393.5) + 3(−285.8)] - [(−84.7) + 3(−241.8)]
ΔH = -1341.2 kJ/mol
Since the enthalpy of the reaction is negative, the reaction is exothermic.
ΔH = [2(−393.5) + 3(−285.8)] - [(−84.7) + 3(−241.8)]
ΔH = -1341.2 kJ/mol
Since the enthalpy of the reaction is negative, the reaction is exothermic.
