The enthalpies of formation of n2o and no at 298 Kelvin and 82 and 90 ...
Enthalpy of the reaction N2O + 1/2 O2 → 2NO
The enthalpy change of a reaction can be determined by subtracting the sum of the enthalpies of formation of the reactants from the sum of the enthalpies of formation of the products.
Given Data:
- Enthalpy of formation of N2O = 82 kJ/mol
- Enthalpy of formation of NO = 90 kJ/mol
Calculating Enthalpy of Reaction:
- Enthalpy of reaction = [2(Enthalpy of formation of NO) - (Enthalpy of formation of N2O + 1/2 Enthalpy of formation of O2)]
- Enthalpy of reaction = [2(90 kJ/mol) - (82 kJ/mol + 1/2(0 kJ/mol))]
- Enthalpy of reaction = [180 kJ/mol - 82 kJ/mol]
- Enthalpy of reaction = 98 kJ/mol
Therefore, the enthalpy change for the reaction N2O + 1/2 O2 → 2NO is 98 kJ/mol. This means that the reaction is exothermic as it releases 98 kJ of energy per mole of reaction.
