Is it possible for a reaction to have a large equilibrium constant but small forward and reverse rate constants? Choose one - A. No, the equilibrium constant and rate constant are both determined by the same thermodynamic parameters. B. Yes, the equilibrium constant is determined by the ratio of the forward and reverse rate constants, not the absolute value of those rates C. No, a large equilibrium constant means that the rate constants must also be large D. Yes, the...
