An exothermic reaction produces two moles of gas from one mole of solid reactant. Will the reaction be spontaneous? O The reaction will be spontaneous if the magnitude of TArS° is smaller than the magnitude of ArHº. O The reaction will always be spontaneous. O The reaction will never be spontaneous. O The reaction will be spontaneous if the magnitude of TArS° is larger than the magnitude of ArHº.
