Answer to Question #67760 in General Chemistry for Debbie Marshall

Question

HELP!!!
Calculate ΔH of the reaction shown below. Balance the equation before beginning the calculation. DO NOT use the Heat of Formations table! Use the heats of formation shown below.


NO(g) + H2O(l) → HNO3(l) + H2(g) + O2(g)

ΔHNO = 44.5 kJ/mol
ΔHH2O = -180 kJ/mol
ΔHHNO3 = -213 kJ/mol
ΔHH2 = 0 kJ/mol
ΔHO2 = 0 kJ/mol
