(Answered) For a gas that obeys the van der waals equation of state

Academics

For a gas that obeys the Van der Waals equation of state, derive the deviation from ideality of the internal energy (i.e. U_actual- U_ideal). At 400K, U_ideal is 14.55 kJ/mol. Plot U as a function of pressure from 1 to 200 atmospheres. Note the one way to do this is to choose a range of molar volumes, calculate both the U_actual and the pressure for each of those volumes and then plot the U_actualvs the pressure that corresponds.

Van der Waals constants: a=5.5088 L^2barmol^-1

b= 0.065144 L/mol
