Question 1 ( Gas Laws ) 1 5 0 k g of ethane ( C 2 H 6 ) is stored in a 1 5

Question 1(Gas Laws)
150kg of ethane (C2H6) is stored in a 15.0m3 tank. For a temperature of 50C estimate the pressure of the gas in the tank assuming that the van der Waals equation is applicable.
The vessel bursts at a pressure of 50atm. Using the method of successive substitution, how much more ethane (kg) can be pumped into the vessel before it bursts?
Plot the compression factor of the gas as a function of pressure for at least 5 pressures between 10 and 50 bar (Use either Excel in combination with Goal Seek or Matlab in combination with a root-finding function). Describe the figure and explain the observation.
p=RT(hat(V))-b-ahat(V)2 where a=27R2Tc264pc and b=RTc8pc
For C2H6
a=0.558Pammol2,b=6.5110-5m3mol
R=8.3145JmolK5,1atm=1.013105Nm2
