Vedclass · Answer

(B) The relationship between the change in enthalpy $(\Delta H)$ and the change in internal energy $(\Delta U)$ is given by the equation: $\Delta H = \Delta U + \Delta n_g RT$. For $\Delta H$ to be equal to $\Delta U$,the term $\Delta n_g$ must be equal to $0$. $\Delta n_g$ is the difference between the sum of the stoichiometric coefficients of gaseous products and gaseous reactants. For option $(B)$: $C_{(s)} + O_{2(g)} \rightarrow CO_{2(g)}$,$\Delta n_g = 1 - 1 = 0$. Therefore,$\Delta H = \Delta U$ for this reaction.

Identify the equation in which the change in enthalpy is equal to the change in internal energy.
