Verified step by step guidance1
Identify the factors that can influence the rate of a chemical reaction: concentration of reactants, temperature, presence of a catalyst, and pressure.
Understand that the concentration of reactants is a key factor because it directly affects the frequency of collisions between reactant molecules, which is necessary for a reaction to occur.
Recognize that according to the rate law, the rate of a reaction is often proportional to the concentration of the reactants raised to a power, which is determined experimentally.
Consider the role of temperature, which affects the kinetic energy of molecules and can increase the rate of reaction by providing more energy to overcome the activation energy barrier.
Evaluate the presence of a catalyst, which can lower the activation energy and increase the reaction rate without being consumed in the process, but does not affect the concentration of reactants.
