Answer 1

Answer #1

For any reaction

Standard enthalpy change of reaction = sum of heat of formation of products- sum of heat of formation of reactants

For the reaction 3NO2(g)+ H2O(l)----->2HNO3(aq)+ NO(g)

Standard enthalpy change= 2* heat of formation of HNO3 (aq)+ Heat of formation of NO- { 3* heat of formation of NO2+ heat of formation of H2O(l)

2*(-207)+91.3- {3*33.2+(-187.8}=-234.5 Kj/mole
