The enthalpy of reaction, `Delta_(1) H`, is

Standard molar enthalpy of formation, Delta_(f) H^(Θ) is just a special case of enthalpy of reaction, Delta_(r) H^(Θ) . Is the Delta_(r) H^(Θ) same as standard molar enthalpy of formation ? Given reason for your answer. CaO (s) + CO_(2) (g) rarr CaCO_(3) (s) , Delta_(f) H^(Θ) = - 178.3 kJ mol^(-1)

Define standard enthalpy of reaction (Delta_(r)H^(0)) . Give an example.

For an endothermic reaction, where Delta H represents the enthalpy of reaction in kJ mol^(-1) , the minimum value for the energy of activation will be

For an endothermic reaction, where Delta H represents the enthalpy of reaction in kJ mol^(-1) , the minimum value for the energy of activation will be

For an endothermic reaction, where Delta H represents the enthalpy of reaction in kJ mol^(-1) , the minimum value for the energy of activation will be
