The activation energy of the reverse reaction has to be calculated. Concept Introduction: The enthalpy of a reaction can be calculated as given below. Δ H r x n = ∑ H f ( p r o d u c t s ) − ∑ H f ( reactants ) The difference between activation energy of forward reaction and that of backward reaction is the enthalpy of that reaction. Mathematically, it can be written as given below. Δ H r x n = E a ( F o r w a r d ) − E a ( r e v e r s e ) For endothermic reaction, Δ H r x n is positive. For exothermic reaction, Δ H r x n is negative.
