N2g o h. 2) And get this result N 2 (g) 2O 2 (g) > 2NO 2 (g) ΔH = 676 kJ 3) You do not need the third equation because N 2 O is not involved in the target equation and cannot be cancelled out with either of the first two equations, It is only present as a distractor and to make you worry because you're not using it in getting the answer 4) Notice also that there are slightly different ΔH. Where q p is the heat of reaction under conditions of constant pressure And so, if a chemical or physical process is carried out at constant pressure with the only work done caused by expansion or contraction, then the heat flow (q p) and enthalpy change (ΔH) for the process are equalThe heat given off when you operate a Bunsen burner is equal to the enthalpy change of the methane. 2 S O 2 (g) O 2 (g) ⇌ 2 S O 3 (g) K p is less than K C for 2 S O 2 ( g ) O 2 ( g ) ⇌ 2 S O 3 ( g ) Δ n = number of moles of gaseous products − number of moles of gaseous reactants.
