1.	Enthalpies of formation of CO(g),CO2(g),N2O(g) and N2O4(g)are–11 0kJ mol−1,–393 kJ mol−1,81 kJ mol–1 and 9.7 kJ mol−1 respectively. Find the value of ΔrH for the reaction: N2O4(g)+3CO(g)→N2O(g)+3CO2(g)
Answer» Enthalpies of formation of $C O_{(g)}, C O_{2 (g)}, N_{2} O_{(g)}$ and $N_{2} O_{4 (g)} a r e - 110 k J m o l^{- 1}, - 393 k J m o l^{- 1}, 81 k J m o l^{- 1}$ and $9.7 k J m o l^{- 1}$ respectively. Find the value of $Δ_{r} H$ for the reaction: $N_{2} O_{4 (g)} + 3 C O_{(g)} \to N_{2} O_{(g)} + 3 C O_{2 (g)}$
