A) The reaction is at equilibrium B) The reaction is exothermic C) The reaction is endothermic D) all of the gasses present are at the same temperature E) the number of moles of gas on both sides of the balanced equation is the same. Q(23) HAH +A at the equilibrium (HA) = 1.65* 10-2 M and [H") = (A-) = 5.44*10-4 M at equilibrium. Kc = A) 1.7 X 10-1 C) 1.7 X 103 D) 1.7 X 104 E) 1.7 X 10% B) 1.7 X 102 A 406 Q(24) Select the statement that best describes a system at equilibrium. A) The reaction is complete because all reactants have become products. B) The reaction has stopped because all of the catalyst has been used. C) As soon as product molecules form, other molecules of product become reactants. D) The reaction stops when the amounts of reactants and products reach equilibrium amounts. E) None of the above Q(25) Which of the following is the expression that relates Kc to Kp? A) Kc = KRT B) KcKp = RTN D) Kp = K.P/RT C) K = KJ(RT) C) K = K.(RTW

Answer 1

22)

Δ n = number of gaseous molecule in product - number of gaseous molecule in reactant

use:

Kp= Kc (RT)^Δn

For Kp = Kc,Δn should be 0
