What is the main reason why increasing the temperature increases the rate of a chemical reaction? A. Increasing the temperature raises the energy of activation (Ea) B. Increasing the temperature lowers the energy of activation (Ea) C. Increasing the temperature increases the number of molecules that have the correct orientation for reacting D. Increasing the temperature increases the concentration of reactant molecules E. Increasing the temperature increases the number of molecules that have enough energy to react.     Tables.pdf Periodic Table with New Elements.pdf
