Compound ΔG∘f (kJ/mol) A +387.7 B +550.7 C +402.0 Use the data given here to calculate the values of ΔG∘rxn at 25 ∘ C for the reaction described by the equation A+B↽−−⇀C If ΔH∘rxn and ΔS∘rxn are both negative values, what drives the spontaneous reaction and in what direction at standard conditions? ΔG∘rxn= kJ The spontaneous reaction is enthalpy-driven to the left. enthalpy-driven to the right. entropy-driven to the right. entropy-driven to the left.
