Question 3: (9 marks) NH3 gas (A) and N2 gas (B) are in equimolar counter-diffusing through a glass tube connected to two large chambers at the two ends of the tube at 25C and 101.3kPa. The length of the tube is 60cm and diameter is 2.57cm. the partial pressure of NH3 at one end is 101.3kPa and at the other end is 6.7kPa. The diffusivity of ammonia that temperature is 2.3105m2/s.
