1. Building on our knowledge of gases: 1.6 mole of CO₂ (g) occupies 3.2 L at T = 300 K. If the gas is compressed isothermally at constant external pressure Pext so that the final volume is 1.2 L, calculate the smallest value Pext can have, assuming that CO₂ satisfies the van der Waals equation of state under these conditions. Calculate the work involved using this value of Pext.

I need help with A and B for this problem. I want to see the detailed steps.
Problem #2: For this problem, one mole of a diatomic ideal gas is taken around a reversible cycle by starting at pressure P, volume V, and temperature T, then in an isochoric process 1 increasing pressure to 6P, then in an isobaric process 2 increasing its volume to 21V, then another isochoric process 3 back to a pressure P, and finally in an isobaric process 4 back to P, V, T. Find the temperature of this gas at the end of process 1, 2, and 3 in terms of the original temperature T. Find the internal energy change in process 1 and in process 2 in terms of P and V. Find the heat transfer in process 1 and in process 2 in terms of P and V.
