For each reaction below, indicate in which direction the equilibrium shifts when the stated
stress is applied to the system. write r if the reaction shifts to the right, l if it shifts to the
left, or nc if there is no change.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
