Cr₂O₇²⁻(aq) + H₂O(l) ⇌ 2CrO₄²⁻(aq) + 2H⁺. What happens to the reaction when the hydrogen ion concentration is increased?
- A. The equilibrium position will shift to the leftCorrect
- B. More of the products will be formed
- C. The reaction will not proceed
- D. The equilibrium position will shift to the right
