Collision Theory: Chemical reactions occur when particles of substances collide with energy greater than or equal to the activation energy and correct particle orientation.
Reaction Conditions: Changing the conditions of a reaction can increase the likelihood of collisions occurring with sufficient energy to react and increase the reaction rate.
Maxwell-Boltzmann Distribution: Not all molecules in a substance have the same amount of energy, and their energies are distributed in a pattern called the Maxwell-Boltzmann distribution.
Effect of Temperature: Increasing the reaction temperature increases the rate of reaction as more collisions of greater energy occur.
Effect of Concentration and Pressure: Increasing the concentration or pressure of a sample increases the rate of reaction by increasing the likelihood of collisions occurring with energy greater than the activation energy.
