About this document
Understanding Chemical Reactions and Rates by Ifra Hassan is a document available to read on EtoBox.
1) Chemical reactions occur on a molecular level when molecules interact and atomic bonds are broken or formed. Physical changes do not involve changes at the molecular level. 2) For a chemical reaction to occur, reactant particles must collide with sufficient energy to overcome the activation energy barrier. Factors like concentration, temperature, pressure, and catalysis affect the collision rate and energies of particles. 3) The rate of a chemical reaction depends on the concentration of reactants. In
