WebThe rate of reaction can be analysed by plotting a graph of mass or volume of product formed against time. The graph shows this for two reactions. The steeper the line, the … WebThere are four main factors that can affect the reaction rate of a chemical reaction: Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.
