Question

I need help with all three please and thank you!

1. In the following reaction at equilibrium, what will happen if more CO(g) is added? COC12(g) CO(g) + Cl2(g) A) reaction will shift to the right B) reaction will shift to the left C) nothing will happen D) the equilibrium constant will change E) not enough information given to predict 2. The following reaction is exothermic (with A and B reactants) and at equilibrium. What will happen if heat is added? A+B 2 C + D A) more C but less D will be produced B) more C and D will be produced C) nothing will happen D) more A and less B will be produced E) more A and B will be produced 3. Gases are placed in an enclosed container at the following concentrations: [NOBr] = 7.13 x 10-2M, [NO) = 1.58 x 10-M, [Br] = 1.29 x 10M The reaction is: 2 NOBr(g) 2 2 NO(g) + Brz(g) Keq = 3.07 x 10 Calculate Q and determine if [NOBr] increases or decreases as equilibrium is establishe A) Q = 2.01 x 102 and [NOBr] increases B) Q = 2.01 x 102 and [NOBr] decreases C) Q = 8.75 x 104 and [NOBr] decreases D) Q = 6.33 x 10 - and [NOBr] increases E) None of the above

Answer 1

Date According If the side is Shifts to Date H to Le-Chatelier principle, concentration of substance on on increased, then the equilibrium opposite side. 2 coch (g) colgate (g) On adding co, equilibrium shifts to left. For an exothermic reaction, if heat is added, the reaction equilibrium shifts to reverse order - At R Ĉ CAD More A & B will be produced Option E is correct 2 No Brig) - 200(g) + Blzig) Q = [NO]²[Br ] [NOBR] 2 (1.58X10-22 (1.29x10-2) - 170 13x10- 22 3 6:33X10-4 Ke = 3.07810-4 goes to Q > Keg, so the reaction reverse order Therefore [No Br] increases Option 8 is correct.
