Calculate the work done in the following reaction at $300 \ K$ and at constant pressure. $(R = 8.314 \ J \ K^{-1} \ mol^{-1})$ $4 \ HCl_{(g)} + O_{2_{(g)}} \rightarrow 2 \ Cl_{2_{(g)}} + 2 \ H_2O_{(g)}$ (in $J$)

In which of the following reactions is $\Delta E = \Delta H$?

What is a $System$ in thermodynamics?

One mole of a non-ideal gas undergoes a change of state ($2.0 \, atm$,$3.0 \, L$,$95 \, K$) $\rightarrow$ ($4.0 \, atm$,$5.0 \, L$,$245 \, K$) with a change in internal energy,$\Delta U = 30.0 \, L \, atm$. The change in enthalpy $\Delta H$ of the process in $L \, atm$ is.

What are extensive properties?

The maximum work done in expanding $16 \, g$ of $O_2$ gas isothermally at $300 \, K$ from an initial volume of $5 \, dm^3$ to a final volume of $25 \, dm^3$ is:
