Rates of Reaction 0.0 / 5 ? ScienceChemical reactionsGCSEAQA Created by: Bev LambourneCreated on: 20-03-14 12:21 What happens if two particles collide but they do not have enough activation energy? DO NOT REACT (BOUNCE APART) 1 of 10 What happens to the rate of a reaction if the temperature is decreased? DECREASES 2 of 10 What happens to the rate of reaction if the concentration of the dissolved reatants is increased? INCREASES 3 of 10 What happens to the rate of reaction if the pressure of gas reactants is increased? INCREASES 4 of 10 What happens to the rate of a reaction if the surface area of a reactant is increased? INCREASES 5 of 10 What does a catalyst do to the rate of reaction? INCREASES 6 of 10 Why can catalysts be reused? NOT USED UP DURING THE REACTION 7 of 10 How can the rate of a chemical reaction be measured? HOW FAST THE REACTANT IS USED UP / PRODUCT IS MADE 8 of 10 Give four ways in which you could increse the rate of a chemical reaction. INCREASE TEMPERATURE; INCREASE CONCENTRATION (PRESSURE); INCREASE STRUCTURE AREA; ADD A CATALYST 9 of 10 Give three ways in which you could decrease the rate of a chemical reaction. DECREASE TEMPERATURE; DECREASE CONCENTRATION (PRESSURE); DECREASE STRUCTURE AREA 10 of 10
