11. How does the addition of H3O* affect the following reaction equilibrium? 2CrO42 (aq, yellow) + 2H30* (aq) Cr2O,2 (aq, orange) + 3H20 (1) -> a. The reaction shifts to the right and the concentration of CrO42 increases. b. The reaction shifts to the right causing the concentration of Cr2072 to decreases and the solution to turns yellow. c. The reaction shifts to the right resulting in a reduction in the concentration of H3O* and an increase in the concentration of Cr2O,2-. d. The reaction shifts to the left and the concentration of CrO42 increases. e. The reaction shifts to the left and the concentration of CrO42 decreases.
