Q
Enthalpy of Formation?
A
standard reaction enthalpy for the formation of compound from its elements each in their standard states.
4
Q
Enthalpy of reaction equation?
A
products - reactants

Q
Enthalpy of combustion?
A
enthalpy change when 1 mole of compound is completely oxidised all reactants and products are in standard state.
