If equilibrium constant K is larger then the product concentration [C] has to be higher than that of reactants and the reaction will proceed to the right with a faster rate.
1 PUN) A reaction with a large equilibrium constant 1) has a fast rate
A large equilibrium constant a. results from the addition of a catalyst to a reaction mixture. b. indicates that the reaction favors the formation of products. c. indicates that the reaction favors the formation of reactants. d. indicates that a reaction has a large rate constant. e. indicates that a reaction has a small rate constant.
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...
A chemical reaction, A+B → P, has the following mechanism: 2A< Ki>A, (fast to equilibrium) A+B&K, ™C (fast to equilibrium), A,+C-k>P+ 2A (slow) where Kį and K2 are the equilibrium constants for the first two reactions, respectively. k3 is the rate constant for the third reaction. (a) [5 points] Based on this mechanism, show that the rate of product (P) formation is: d[P] – k[A[B], where k is the rate constant of the overall reaction. Write k in terms of...
