• When enzymes are present in very low concentrations, their effect on the rate of a reaction can be described using first-order kinetics. If the concentration of a catalyzing enzyme is changed from 3.45 × 10−3 M to 5.38 × 10−1 M, by what factor does the rate of the reaction change ?

• Answer:

  Divide the larger number by the smaller number.
