Question

11) The reaction quotient, ec, for a reaction has a value of 75 while the equilibrium constant, Kc, has a value of 195. Which of the following statements is accurate? A) The concentrations of the products will be much smaller than the concentrations of the reactants when the system is at equilibrium. (B The reaction must proceed to the right to C) The concentrations products will be about the same as the concentrations of the reactants when the system is at equilibrium. D) The reaction must proceed to the left to establish equilibrium. E) None of the above statements is accurate. 11) 12) The two equilibrium constants for the same reaction, Kc and Kp, will always equal one another when A) all the reactants and products are gases. B) in the reaction equation, the number of moles of gaseous products is smaller than the number of moles of aseous reactants. products number moles of gaseous C in the reaction equation, the number of moles of gaseous equals the of reactants equals that of the products. D) in the reaction equation, the total number of moles of reactants is greater than the number of moles of E in the reaction equation, the number of moles of gaseous products gaseous reactants. 12)

Explanation / Answer

11.

when Q is less than Kc , the reaction will favour more reactants, because when Q is less products is less and reactants will be more.... so equilibrium will be achieved by forming more products.

12.

Kp = Kc(RT)delta ng

when delta ng = 0, Kp = Kc
