2022-E - Question 8. Internal energy in gas expansion [1 point]

For a chemical process taking place at constant pressure, the enthalpy change is $\Delta H = +30\text{ kJ}$. During the process, the system expands and does $25\text{ kJ}$ of work on the surroundings. What is the change in internal energy ($\Delta U$) for this reaction?
