2 - a - Calculate the work done for 10 moles of CH4 during an expansion from an initial volume of 5.0 L to a final volume of 10.0 L. During expansion, the pressure of CH4 varies from an initial value of 50 atm to a final pressure of 25 atm. When the pressure reaches 25 atm, the expansion stops due to the fact that the gas enters into mechanical equilibrium with the external environment, whose pressure is also maintained at 25 atm. The process involves high pressures, CH4 cannot be considered as an ideal gas. Develop all calculations in detail. b - Is it possible, through an isothermal compression, to liquefy CH4 from its initial state of volume = 5.0 L and pressure = 50 atm)? Justify your answer. Develop all calculations in detail. An answer without justification wil not be considered. Parameters of the van der Waals equation for CH4, where P is pressure and V the volume: nRT n'a p= V – nb a = 2.26 atm*L^2*mol^-2 b = 0.043 L*mol^-1 Critical CH4 temperature: – 82.5 °C
