Rates of Reaction 0.0 / 5 ? ChemistryRates of reactionOtherNone Created by: Kathryn Boulton-PrattCreated on: 19-05-14 21:51 How can rate be measured? Amount of reactant used or product produced in a given time 1 of 7 What is collision thoery? Particles must 1) collide and 2) have enough energy to react 2 of 7 What is activation energy Minimum amount of energy needed for a reaction to happen 3 of 7 Name 3 things that can change the rate of a reaction Temperature, Surface area, Concentration, Catalyst 4 of 7 What happens to the rate of reaction if the concentration of a solution is doubled? Rate doubles 5 of 7 What is a catalyst? Catalyst changes the rate of reaction but is itself unchanged at the end of the reaction. 6 of 7 Why does increasing the surface area increase the rate of a reaction? Larger surface area means there are more particles available for collision so collisions happen more often and more of them are successful 7 of 7
