Define Enthalpy Change
Heat evolved or absorbed during a reaction happening at a constant pressure
Define mean bond enthalpy
The enthalpy change when one mole of a specific type of bond is broken and averaged over
different compounds
Bond Dissociation enthalpy
The enthalpy change required to break a covalent bond with all species in their gaseous state
Standard molar enthalpy of formation
Enthalpy change from 1mole of substance FORMED from its C.E in S.C with reac ∏ in their
S.S
Standard molar enthalpy of combustion
Enthalpy change when 1 mole of substance is completely burnt in O2 under S.C all prod in S.S
What does Hess' Law state
That the enthalpy change for a chemical reaction is the same, whatever route is taken from
reactants to products
