Two very large tanks, maintained at 323 k and 1 atm total system pressure, are connected by a 0.1-m-diameter circular duct which is 5 m in length. tank 1 contains a uniform gas of 60 mol% acetone and 40 mol% air, whereas tank 2 contains a uniform gas of 10 mol% acetone and 90 mol% air. determine the initial rate of acetone transfer between the two tanks. the gas diffusivity of acetone in air at 298 k and 1 atm is 0: 093 cm2/s.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
