Question

Tn Consider thefollowing reaction at equilibrium What effect will adding COg have on the systemt1 A) No effect will be observed since CO) is not Included in the equilibrium expression. e reaction will shift to the left in the direction of reactants ) The reaction will shift to the right in the direction of products. D) The equilibrium constant will decrease 1) The equilibrium constant will increase 18 18) Which of the following statements is FALSE A) K 1 implies that the reaction is very fast at producing products 1D) When K 1, the reverse reaction is favored and the forward reaction does not proceed t great extent When K1, the forward reaction is favored and essentially goes to completion. D) When K 1, neither the forward or reverse reaction is strongly favored, and about the same ) None of the above. amount of reactants and products exist at equilibrium. 19) 19) Identify the species oxidized 2 Al3+(aq) + 2 Fe(s) 2 Al(s) + 3 Fe2+(aq) A) Fe B) Al C) Fe2 D) A13 E) This is not an oxidation-reduction reaction 20)

Explanation / Answer

17.

when CO2 is added to the equilibrium mixture, the equilibrium will shift to right in the direction of products.

option "c" is correct

18.

all are correct statements

19.

oxidised means losing of electrons.

so in the reaction "Fe" looses electrons

So "Fe" is oxidised.

so option "A" is correct
