And what you've all been waiting for
Here's another kind of possible problem: Using the equation governing the flow of sugar across a membrane from the following equation
And given that
P= 0.02 cm/sec
the area of the membrane between the two solutions is 2 cm2
Solution left side of the membrane = 0.4M
Solution right side of the membrane = 0.1M
What is the rate of diffusion across the membrane for the following concentrations? This kind of problem requires straightforward plug-and-chugging...
0.02cm/sec x 2 cm2 x (0.4M sugar - 0.1M sugar)
= 0.012 moles/second
What would happen if we doubled the permeability constant?
What if we doubled the area of the membrane?
What if we doubled the concentration on the left?
