QUESTION 2 Consider the following reaction and its equilibrium constant: SO2(g) + NO 2(0) SO 3(g) + NO(g) K c = 0.33 A reaction mixture contains 0.41 M SO 2, 0.13 M NO 2.0.11 M SO 3 and 0.13 M NO. Which of the following statements is TRUE concerning this system? The reaction quotient will decrease The reaction will shift in the direction of reactants. The reaction will shift in the direction of products, The equilibrium constant will decrease. The system is at equilibrium ООО QUESTION 3 Determine the value of Kc for the following reaction if the equilibrium concentrations are as follows: [PBr 5l eq - 0.58 M, [PBr 3l eq - 0.23 M, (Br al eq 6.6 M PBr 5(g) = PBr 3( ) + Br 2(g) O 0.37 O 4.2 O 0.93 0.76 2.7

Answer 1

Question 2:

The given reaction is S02() + N02(8) 303 (7) + 14069) The Reaction quotient (Q) of this reaction 9 : [53] [No [so₂] [NO] is Griven concentrations are: - [502] = 0.41M; [NO] = 0.13 M; [303] = 0.11M and [no] =0.13 M. putting the values in the above equations [303] [NOS 0:11MX013 M Iso₂] [NO] 0.41 MX 0.18M we get, os

products --> 8 = 0.268 And given ke=0.33. SO 8 ikke, then reactante) and the reaction will shift right. so option 1. The reaction quotient will decrease.

And option 3. The reaction will shift in the direction of products. This two statements are TRUE.

Option 1 and 3 are the correct answer.

Question 3:

The given reaction is- PBrg (8) PBrz (6) + Brz. (6) ke of this reaction can be written as, ke [PBrz] [ Bro] [Perg Geiven ;- [Perbeq = 0.56M; [PB93] 09.=0.73M and [Br.] eq = 6.6M

NOW, ke [P Brg] [ Bro О.23м х 6 • GMT [PBTS О. 5. М - 2.1 м 30, ke с1 М.

Option 5 is the correct answer.
