II$.-$Assuming ideal gas behavior, calculate the heat that must be transferred

in the following systems. Also make the sketch of the system

and the disaggregated energy balance.

The N$2$ contained in a $5$L reactor at an initial pressure of $3$ bar is cooled

$90\backslash$deg C to $30\backslash$deg C

Use the Cp of N$2$ as $29\mathrm{.}124$ J$/$mol K
