For each reaction, calculate ΔH∘rxn, ΔS∘rxn, and ΔGrxn at 33 ∘C. Part APart complete N2O4(g)→2NO2(g) Express your answer using three significant figures. ΔH∘rxn = 57.2 kJ Previous Answers Correct Part B N2O4(g)→2NO2(g) Express your answer using three significant figures. ΔS∘rxn = J/K Previous AnswersRequest Answer Incorrect; Try Again; 3 attempts remaining Part CPart complete N2O4(g)→2NO2(g) Express your answer using two significant figures. ΔG∘rxn = 3.4 kJ Previous Answers Correct Part DPart complete State whether or not the reaction in part A is spontaneous. If the reaction is not spontaneous, would a change in temperature make it spontaneous? If so, should the temperature be raised or lowered from 33 ∘C? Express your answer using three significant figures. The reaction is spontaneous. The reaction can be made spontaneous by raising the temperature. The reaction can be made spontaneous by lowering the temperature. The reaction can not be spontaneous at any temperature. Previous Answers Correct Part E NH4Cl(s)→HCl(g)+NH3(g) E
