WebGet ready for your exams with this BBC Bitesize GCSE Chemistry rates of reaction and energy changes (Edexcel) exam preparation guide. WebWe can measure the quantity of reactant used up, or quantity of product formed in a reaction. This is the second factor that we need to know in order to calculate the rate of a reaction. Reactions have an end point. When one of the reactants has been completely used up, the reaction will stop. This is the end-point of the reaction, meaning that ...

WebReversible reactions can reach a point called equilibrium. Here the rate of the forward reaction is equal to the rate of the reverse reaction. The reactions continue but the concentration of reactants and products remains constant. If the reaction conditions are changed this can affect the position of equilibrium: 1.
WebThe rate of reaction is shown to be dependent on the concentration terms of reactant A and reactant B. Then, Rate of reaction ∝ [A] α [B] β. or Rate = K [A] α [B] β. This expression …
