the enzymes involved become inactive

the concentration of the reactants is increased
|
Detailed explanation-1: -Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.
Detailed explanation-2: -A catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction. Catalysis is the process of adding a catalyst to facilitate a reaction.
Detailed explanation-3: -When the reactants are heated, the average kinetic energy of the molecules increases. This means that more molecules are moving faster and hitting each other with more energy. If more molecules hit each other with enough energy to react, then the rate of the reaction increases.
