The enzyme carbonic anhydrase catalyses the hydration of carbon dioxide. In a biochemical investigation, the rate of hydration of carbon dioxide was measured with and without the enzyme present.
With carbonic anhydrase present, 4.8×1054.8 \times 10^54.8×105 molecules of carbon dioxide were converted per second. Without the enzyme, the uncatalysed reaction rate was 1.5×10−41.5 \times 10^{-4}1.5×10−4 molecules of carbon dioxide converted per second.
Calculate by how many times the rate of reaction is greater with the enzyme present than without. Give your answer in standard form.
