Which of the following statements is true

Which of the following statements is true
  1. $\Delta \mathrm{E}$ is always greater than $\Delta \mathrm{H}$
  2. $\Delta \mathrm{E}$ is always less than $\Delta \mathrm{H}$
  3. $\Delta \mathrm{E}$ may be lesser or greater or equal to $\Delta \mathrm{H}$
  4. $\Delta \mathrm{E}$ is always proportional to $\Delta \mathrm{H}$

Solution

$\Delta \mathrm{E}$ may be greater or lesser or equal to $\Delta \mathrm{H}$
$\therefore \Delta \mathrm{H}=\Delta \mathrm{E}+\mathrm{P} \Delta \mathrm{V}=\Delta \mathrm{E}+\Delta \mathrm{nRT}$ *
