Problem 37

A gas is confined to a cylinder under constant atmospheric pressure, as illustrated in Figure $5.4 .$ When the gas undergoes a particular chemical reaction, it absorbs 824 $\mathrm{J}$ of heat from its surroundings and has 0.65 $\mathrm{kJ}$ of $P-V$ work done on it by its surroundings. What are the values of $\Delta H$ and $\Delta E$ for this process?

$$\Delta E=1.47 \mathrm{kJ}$$
$$\Delta \mathrm{H}=0.824 \mathrm{kJ}$$
