A layer with negligible thickness containing 10.0 nmol of methanol (D = 1.6 10 - 9
Question:
A layer with negligible thickness containing 10.0 nmol of methanol (D = 1.6 × 10-9 m2/s) was placed in a tube of water 5.00 cm in diameter and allowed to spread by diffusion. Using Equation 22-25, prepare a graph showing the Gaussian concentration profile of the methanol zone after 1.00, 10.0, and 100 min. Prepare a second graph showing the same experiment with the enzyme ribonuclease (D = 0.12 × 10-9 m2/s).
Equation 22-25
