WebA reactant is a substance that takes part in a chemical reaction and is present at the start of the reaction. Reactants are transformed into products during the reaction. →What is a product? A product is a substance that is formed as a result of a chemical reaction. Products are formed from reactants during the reaction. →What is a catalyst? WebGCSE Chemistry – Graphs to Calculate Rates of Reaction Mean rate of reaction can be calculated. If we work out the overall change in y value (i.e. product formed or reactants used up) then divide by the total time taken for the reaction, we can calculate the mean rate of reaction.
