The forward reaction will proceed to establish equilibrium. The reverse reaction will proceed to establish equilibrium. 0.375 points QUESTION 11 1. Which of the following is a true statement about chemical equilibria in general? At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. At equilibrium, the total concentration of products equals the total concentration of reactants, that is [products] = [reactants]. There is only one set of equilibrium concentrations that equals the K c value. Equilibrium is the result of the cessation of all chemical change. 0.375 points QUESTION 12 1. Write the equilibrium expression, Q c , for the following chemical reaction 3ClO 2 - ( aq ) ↔ 2ClO 3 - ( aq ) + Cl - ( aq ) 3[ClO 2 - ] / 2[ClO 3 - ] [Cl - ] 2[ClO 3 - ][Cl - ] / 3[ClO 2 - ] [ClO 2 - ] 3 / [ClO 3 - ] 2 [Cl - ] [ClO 3 - ] 2 [Cl - ] / [ClO 2 - ] 3 0.375 points QUESTION 13 1. The acid dissociation constant K a equals 1.26 x 10 -2 for HSO 4 - and is 5.6 x 10 -10 for NH 4 + . Which statement about the following equilibrium is correct? HSO 4 - ( aq ) + NH 3 ( aq ) ↔ SO 4 2- ( aq ) + NH 4 + ( aq ) The reactants will be favored because ammonia is a stronger base than the sulfate anion.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
