Q. One mole of a non-ideal gas undergoes a change of state $\left(\right.2.0 \, atm,3.0 \, L,95 \, K\left.\right)$ $ \rightarrow \left(\right.4 \, atm, \, 5 \, L, \, 245 \, K\left.\right)$ with a change in internal energy, $\Delta E=30.0 \, L \, atm.$ The change in enthalpy, $\Delta H$ , of the process in L atm is

Solution:

$\Delta H=\Delta E+\Delta \left(\right.PV\left.\right)$
$\Delta H=30+\left(4 \times 5 - 2 \times 3\right)=44Latm$
