A student begins a kinetics experiment with a solution containing 0.050 % starch. At time zero (t = 0.00 min), the student adds an enzyme that catalyzes the decomposition of starch. At t = 1.00 min, the concentration of starch has decreased to 0.028 %. Compute the average rate of disappearance of starch. Specify your answer in units of % starch/min
