WebNov 26, 2024 · Affect on Reaction Rate. temperature. increasing temperature increases reaction rate. pressure. increasing pressure increases reaction rate. concentration. in a solution, increasing the amount of reactants increases the reaction rate. state of matter. gases react more readily than liquids, which react more readily than solids. WebThe rate of a chemical reaction is defined as the rate of change in concentration of a reactant or product divided by its coefficient from the balanced equation. A negative sign is used with rates of change of reactants and a positive sign with those of products, ensuring that the reaction rate is always a positive quantity.
