Q5: The gas CO₂ is diffusing at steady state through a tube 20 cm long having a diameter of 1cm at 350k (Stagnant diffusion). The total pressure is constant at 101.32 kpa. The partial pressure of CO₂ at one end is 60.78 kpa and 10.13 kpa at other end. The diffusivity DAB is 0.167 cm²/s at 298k, calculate (1) The rate of CO₂ if the partial pressure remains constant. (2) calculate the total pressure to double the transfer rate.

V. W. Th To %3D Room temperature T = 293 K V V. Vp The gas volume changes from Vp to Va at constant temperature T. The cartoon on the right shows a piston of gas undergoing this compression while submerged in a container of room temperature water, which acts as a reservoir. The initial state of this process is a piston containing 2 moles of a monatomic gas at Tc = 293 K (room temperature water) and volume V = a 1.0 m. The gas is compressed until V, = 0.2 m. During the compression, the heat bath of room temperature water maintains the temperature of the gas at T 293 K. Calculate the work done in joules by the gas during this process. Do not include units in your answer. Be careful to use the standard sign convention for work done by the gas. Write your numerical answer in normal form as described above in the instructions to this worksheet.
