(E) X
2. Which letter corresponds to the change in energy for the overall reaction?
(A) A
(B) B
(C) C
(D) Y
(E) X
3. Statement I Statement II
The reaction shown above is exothermic. BECAUSE   Energy difference B is greater than energy difference A.
4. Statement I Statement II
A system is at equilibrium when the rate of the forward reaction is equal to the rate of the reverse reactions. BECAUSE   At equilibrium, the concentration of the products is equal to that of the reactants.
5. Which of the following statements best describes the condition(s) needed for a successful formation of a product in a chemical reaction?
(A) The collision must involve a sufficient amount of energy, provided from the motion of the particles, to overcome the activation energy.
(B) The relative orientation of the particles has little or no effect on the formation of the product.
(C) The relative orientation of the particles has an effect only if the kinetic energy of the particles is below some minimum value.
(D) The relative orientation of the particles must allow for formation of the new bonds in the product.
(E) The energy of the incoming particles must be above a certain minimum value and the relative orientation of the particles must allow for formation of new bonds in the product.
