Chemical reactions occur when molecules or atoms collide so that the bonds between atones break and new bonds form Breaking the bonds of the reactants requires energy, whereas, bond formation releases energy Select the statements regarding energy changes dung a reason that are true if the heat of reaction, Delta H, is positive, the energy of the products is tower than toe energy to the L - reactants and the reaction Is exothermic. the activation energy, E_a, of the forward reaction is the difference between the energy of the products and the energy of the transition state the energy of a collision between atoms or molecules must be greater than or equal to the activation energy, E_a. for bonds to be broken When the activation energy is low. the reaction rate is slow. Decreasing the temperature decreases the kinetic energy of the reactants, and the reason goes Reactants must collide, with proper orientation and with energy greater than or equal to the activation energy for a reaction to occur. increasing the concentration of reactants increases the number of occasions. and the reaction goes faster.
