Question

Which is not the correct relation between enthalpy $\Delta H$ and intrinsic energy $\Delta E$

• A. $\Delta H=\Delta E+P\Delta V$
• B. $\Delta H=\Delta E+nRT$
• C. $\Delta H=\Delta E-P\Delta V$
• D. $\Delta E=\Delta H-P\Delta V$

Answer 1

The correct option is C $\Delta H=\Delta E-P\Delta V$

This is a direct application of the first law of thermodynamics, $q_p=\Delta H$, $w=-P\Delta V$
