1. Increase Temperature: Heating up the reactants provides them with more kinetic energy. This leads to more frequent and energetic collisions between molecules, increasing the likelihood of successful collisions that result in the formation of products.
2. Increase Concentration: A higher concentration of reactants means there are more molecules in a given space. This leads to more frequent collisions between the reactants, again increasing the likelihood of successful reactions.
3. Add a Catalyst: A catalyst is a substance that speeds up a reaction without being consumed in the process. Catalysts work by providing an alternative pathway for the reaction with a lower activation energy. This means the reactants need less energy to overcome the activation barrier and form products.
