Two very large tanks, maintained at 323 k and 1 atm total system pressure, are connected by 0.1 m diameter circular duct, which is 5 min length. tank no. 1 contains a uniform gas mixture of 60 mol% acetone and 40 mol % air, whereas tank no. 2 contains a uniform gas mixture of 10 mol% acetone and 90 mol% air. determine the initial rate of acetone transfer between the two tanks. list the reason(s) why this process is considered "pseudo steady state"
