Calculate ΔH° for each of the following reactions, which occur in the atmosphere.
Calculate ΔH° for each of the following reactions, which occur in the atmosphere.
(a) C2H4(g) + O3(g) → CH3CHO(g) + O2(g)
(b) O3(g) + NO(g) → NO2(g) +O2(g)
(c) SO3(g) + H2O(l) → H2SO4(aq)
(d) 2 NO(g) + O2(g) → 2 NO2(g)
Homework Answers
A) C2H4(g) + O3(g) -> CH3CHO(g) + O2
C2H4=52.47 kJ/mol
O3= 142.67 kj/mol
CH3CHO=-170.7kJ/mol
O2= 0kJ/mol
(-170.7+ 0) - (52.47+142.67) = 365.84 kJ/mol
