$\Delta H = \Delta U$

Vedclass · Answer

(B) 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 reactions involving only solids or liquids,there is no change in the number of moles of gas,so $\Delta n_g = 0$. Therefore,$\Delta H = \Delta U + (0)RT$,which simplifies to $\Delta H = \Delta U$.

Explain: Enthalpy as a state function.

One mole of a non-ideal gas undergoes a change of state ($2.0 \, atm$,$3.0 \, L$,$95 \, K$) $\rightarrow$ ($4.0 \, atm$,$5.0 \, L$,$245 \, K$) with a change in internal energy,$\Delta U = 30.0 \, L \, atm$. The change in enthalpy $\Delta H$ of the process in $L \, atm$ is.
