Q/ Air is to be bubbled through the solution in the reactor CSTR, in order to strip out of the solution trace amounts of a solvent that have contaminated the water. The rate of loss of the solvent from the solution can be characterized by the equation r = -0.03/min c, where c is the solvent concentration. What fraction of the solvent will be removed from the water as it passes through the reactor with residence time is 26.4 min.
