An industrial biochemist investigated the rate of hydrogen peroxide decomposition. With the enzyme catalase present, 7.2×1047.2 \times 10^47.2×104 molecules of substrate were decomposed per second. Without the enzyme, the uncatalyzed rate of decomposition under identical conditions was 1.6×10−61.6 \times 10^{-6}1.6×10−6 molecules of substrate per second.
Calculate how many times greater the rate of reaction is with catalase present. Give your answer in standard form.
