Chemistry

1) What is the enthalpy of reaction,ΔHrxn for the reaction of nitrogen gas with oxygengas to produce NO2(g), based on the followinginformation? These reactions are not at standard state or at 298K.

N2(g) + O2(g) → 2 NO(g); ΔH =83.1 kJ


2 NO2(g) → 2 NO(g) + O2(g); ΔH =-141.7 kJ


Report your answer in kJ to 1 decimal place.

2)What is the value of ΔHrxn if thereaction below is reversed? In otherwords, PCl5 becomes the reactant. Report youranswer in kJ to 1 decimal place.
PCl3(g) + Cl2(g) → PCl5(g);ΔHrxn = 414.7
