WebJan 11, 2024 · h = 6 or h = -6. Since there are two different values for h, statement one alone is not sufficient to answer the question. We can eliminate answer choices A and D. … WebWhen the reaction is reversed, the equilibrium constant (Keq) value becomes reciprocal to the value of the equilibrium constant for a forward reaction. Therefore, the Keq of equation (2) can be calculated as-Keq = 1/0.05 = 20. Your question seems to be missing crucial information but we still tried to answer it as best as we could.
