Which of the following statements is incorrect concerning the thermochemical equation below? 2SO₃(g)→ 2SO₂(g)+ O₂(g); ΔH° = 198 kJ A)The enthalpy of the reactants exceeds that of the products. B)The reaction is endothermic. C)For the reaction 2SO₂(g)+ O₂(g)→ 2SO₃(g),ΔH° = -198 kJ. D)The external pressure is 1 atm. E)For every mole of SO₃(g)consumed,99 kJ of heat at constant pressure is consumed as well.
