Initial conditions $21\mathrm{.}7$ bar, $298$ K and $1000$ cm$3$

$$mol$-1$ is $10$ moles of ethylene

gas, isothermally $100$ cm$3$

It is compressed to $$mol$-1$ volume value. The following, ethylene

It is essential that the equation that best describes the behavior of the gas is the van der Waals equation of state.

determine:

a$)$ The pressure value $($kPa$)$ to be reached as a result of the compression process.

b$)$ The amount of work required to perform the compression process $($kJ$).$
