Rate Of Reaction 0.0 / 5 ChemistryRate of reactionGCSEAQA Created by: laurenbendallCreated on: 11-06-18 14:58 What is the equation for rate of reaction? Mean rate of reaction = around of reactant used / time taken 1 of 17 What are Rates of Reaction? Pressure, Concentration, Catalyst, Temperature, Surface Area 2 of 17 What is a Reversible reaction? Where the products of reaction can react to produce original reactants 3 of 17 What is Equilibrium? Reversible reaction takes place in closed system then a state of equilibrium will always be reached 4 of 17 What happens when amount of reactants & products reach a balance? Concentration stop changing 5 of 17 What happens when there is a closed system? None of reactants or products can escape 6 of 17 What happens to Red litmus paper? Blue alkali present 7 of 17 What happens to blue litmus paper? Red acid present 8 of 17 What is HCL? An acid 9 of 17 What is NH3? An alkali 10 of 17 What are the dependent Variables? Volume of gas, Temperature change, Colour change/ opaqueness, Change in mass 11 of 17 What is a dependant variable? Measured 12 of 17 What is a Independent Variable? What is changing 13 of 17 What is a control variable? Stays the same 14 of 17 How do you speed up a reaction? Add a catalyst, increase temp, increase pressure/concentration, increase surface area. 15 of 17 What is a chemical reaction? Particles collide with enough energy 16 of 17 What are most reactions? One way 17 of 17
