The total internal energy change for a reversible isothermal cycle is

Which expression is correct for the work done in adiabatic reversible expansion of an ideal gas?

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

Which of the following thermodynamic properties is a path function?

Identify the pair in which both are not extensive properties.

For the reaction of nitrogen with hydrogen to form ammonia,$\Delta H^o = -92.2 \ kJ/mol$. If the reaction is carried out at a constant pressure of $20.0 \ atm$ and a volume change of $-1.16 \ L$,calculate the change in internal energy $(\Delta U)$ in $kJ$.
