Vedclass · Answer

(C) The relationship between enthalpy change $(\Delta H)$ and internal energy change $(\Delta U)$ is given by the equation: $\Delta H = \Delta U + \Delta n_{(g)}RT$. For the reaction $C_{(s)} + O_{2_{(g)}} \rightarrow CO_{2_{(g)}}$,the change in the number of moles of gaseous species is $\Delta n_{(g)} = n_{p(g)} - n_{r(g)} = 1 - 1 = 0$. Since $\Delta n_{(g)} = 0$,the equation becomes $\Delta H = \Delta U + (0)RT$,which simplifies to $\Delta H = \Delta U$.

For the reaction $C_{(s)} + O_{2_{(g)}} \rightarrow CO_{2_{(g)}}$,which of the following is true?
