Vedclass · Answer

(A) In the given energy profile diagram for the reaction $R 	o P$:$a$ represents the potential energy of the reactant $R$ relative to the baseline.$b$ represents the potential energy of the product $P$ relative to the baseline.However,looking at the diagram,$a$ is the energy of $R$ and $b$ is the energy of $P$ relative to the same reference level.The enthalpy change of the reaction,$\Delta H^o$,is defined as the difference between the potential energy of the products and the potential energy of the reactants.$\Delta H^o = E_P - E_R$From the diagram,$E_P = b$ and $E_R = a$.Therefore,$\Delta H^o = b - a$.

The energy diagram for a reaction $R \to P$ is shown below. The $\Delta H^o$ for the reaction will be:
