In thermodynamics,a process is called reversible when

For which one of the following reactions,$\Delta H$ is not equal to $\Delta E$?

Identify the correct equation relating enthalpy $(H)$ and internal energy $(E)$.

An ideal gas at $300 \, K$ expands from a volume of $1 \times 10^{-3} \, m^3$ to $1 \times 10^{-2} \, m^3$ against a constant external pressure of $1 \times 10^5 \, N \, m^{-2}$. Calculate the work done.
