Question Answer
Catalyst Substance that changes the rate of reaction but emerges chemically unchanged at the end of the reaction
Increasing surface area Increases the rate of reaction
Activation energy The minimum amount of energy needed for a reaction to occur is called its activation energy
Collision frequency The number of successful collisions per second. Higher collision frequency leads to a higher rate of reaction
Enzymes Proteins that acts as catalysts in biological processes
Denatured molecule One that has changed shape. Enzymes can be denatured by changes in temperature or pH
Rate of reaction Speed at which products are turned into reactants
