For an endothermic reaction, where ΔH represents the enthalpy of the reaction in kJ/mol, the minimum value for the energy of activation will be:
For an endothermic reaction, energy of activation is Ea and enthalpy of reaction is ΔH (both of these in kJ/mol). Minimum value of Ea will be:
For an endothermic reaction where Δ H represents the enthalpy of the reaction in kJ mol−1, the minimum value for the energy of activation will be.
