How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case, H2O2 will produce more O2, in return the kpa/min will go up. What do you think will happen to the rate of reaction if the concentration of…
