Consider the reaction below. The reaction quotient for a specific moment is 1.11. 10². If the equilibrium constant is 3.87 10², what needs to happen in order for the reaction to reach equilibria? Select all that apply. 1A+2B 3C There will be a net gain in reactant. There will be a net gain in product. The forward reaction will procede more than the reverse reaction. The reverse reaction will occur more than the forward reaction. The system will shift to the left. The system will shift to the right.
Which of the following statements is TRUE? If Q < K, the reaction proceeding to the left is much faster than the reaction proceeding to the right. If Q < K, it means the reverse reaction will proceed to form more reactants. Because the equilibrium is always dynamic, Q can never be equal to K. If Q = K, it means the reaction is not at equilibrium. If Q > K, it means the reverse reaction will proceed to form more reactants.
