A pipe of length I connects to tanks with a mixture of the same gas. In these tanks a trace amount of a second gas is maintained at fixed concentrations n and n. The gas in the pipe and tanks has a diffusivity D. What is the concentration n* of the second gas in the tube at a distance x = 0.8L away from the tank with concentration n*? Select one: a. O b. n* = n² +0.8(n² — n†) O c. n* = 0.5(n² + n²₂) n* = n† +0.8(n† — n²) - O d. n* = n₁ +0.8D(n − n)
