29 (6 pts) How do concentration of reactants, temperature and catalysts affect the rate of a chemical reaction? Explain. Concentration of reactants: mcreases more collisions within the reactants. collisions Temperature: Increase in temperature causes increase in more and more energy in collisions. (increases rate? Catalyst: Lowens energy of activation of reactants cate? (increases rutes
