The Law of Mass Action tells us that the time, T, taken by achemical to create a quantity xo of the product (inmolecules) is given by kdx T = * (a- xMb - x) where a and b are initial quantities of the two ingredients used tomake the product, and k is a positive constant. Suppose 0 < a < b. a) Find the time taken to make a quantity xo * of the product. b) What happens to T as xo -a?
