ChemistryRate of reactionGCSEAQA Created by: 3mily05Created on: 10-10-19 17:08 Rate of Reaction How quickly reactants are used up or products are made 1 of 14 Rate of reaction Equation Mean Rate of reaction = amount of reactant used ÷ time 2 of 14 Ways to measure Rate of reaction: ... 3 of 14 Ways to measure Rate of reaction 1 Volume of gas produced 4 of 14 Ways to measure Rate of reaction 2 Formation of a solid product 5 of 14 Ways to measure Rate of reaction 3 Change in mass 6 of 14 Calculating rates from graphs using a tangent: ... 7 of 14 Part 1 At start steep slope (high gradient) so fast reaction 8 of 14 Part 2 As slope becomes less steep (lower gradient) reaction is slowing 9 of 14 Part 3 Flat line (zero gradient) shows reaction has finished 10 of 14 Equilibrium: ... 11 of 14 Reversible Reaction A chemical reaction where the products can turn back to the reactants 12 of 14 Dynamic Equilibrium When the forwards and backwards and backwards reactions happen at the same rate in a closed system. 13 of 14 Le Charteliers Principle A reaction at equilibrium will act to oppose any change made to it 14 of 14
