Rate of reactions 0.0 / 5 ? ChemistryRate of reactionGCSEAQA Created by: Anisaqosja29Created on: 07-11-19 20:46 What can be used to follow a rate of reaction ? volume of a gas produced 1 of 10 What will not increase a rate of reaction ? A decrease in the surface area of solid particles 2 of 10 What does a catalyst do to a reaction ? increases the rate of reaction 3 of 10 A process that always requires energy ? breaking bonds 4 of 10 Why do not all collisions between reactive molecules result in a reaction ? they do not all have enough energy 5 of 10 What name is given to the amount of energy needed for particles to react ? activation energy 6 of 10 Why does increasing the concentration of reactants increase the rate of reaction ? there are more collisions per second 7 of 10 Why does reaction rate increase as the temp increases ? at higher temperatures particles move faster and collide more often 8 of 10 What is a successful collision ? enough energy is transferred for particles to react 9 of 10 mean rate of reaction = quantity of product formed / time taken 10 of 10
