Problem$-4$

An ideal gas within a piston$-$cylinder assembly executes a Carnot power cycle. as shown in Below Figure. The isothermal compression occurs at $300$ K from $90$ kPa to $120$ kPa $.$ If the thermal efficiency is $\backslash (60\backslash \%\backslash ),$ determine $($a$)$ the temperature of the isothermal expansion, in K $,$ and $($b$)$ the net work developed, in kJ per kmol of gas.
