Please help I am getting 2 different answers! Modesto Junior College - CHEM 143-Fall14-PANDEY: HW 16 ms/mod/ibis/view.php?id=1407587 Caloulator Calculator Periodic Table 1 of 16 Incorrect Mapd Chemical reactions occur when molecules or atoms collide, the bonds between atoms are broken, and new bonds are formed. Breaking the bonds of the reactants requires energy; bond formation releases energy Which of the following statements regarding energy changes during a reaction are true? Decreasing the temperature decreases the kinetic energy of the reactants, adhe reaction goes When the activation energy is high, the reaction rate is fast. Increasing the amount of reactants increases the number o co sions, and the reaction goes more faster The activation energy(Ea) is the energy difference between the energy of the products and the energy of the reactants. Reactants must collide, with proper orientation with energy greater than or equal to the activation energy for a reaction to occur endothermic. rthe eneray of the products is lower than the energy of the reactants, the reaction is The energy of a collision between atoms or molecules must be greater than or equal to the activation energy (E) for bonds tobe broken.
