Question

DILUTOWY EGUm Nitrous Cher = Objective knowledge Check Question 6 At a certain temperature, the equilibrium constant K for the following reaction is 999.: Br (8) + OCI,(g) - BrOCI(g) + BECI(g) Use this information to complete the following table. Suppose a 44. L reaction vessel is filled with 0.76 mol of Broci and 0.76 mol of Bral. What can you say about the composition of the mixture in the vessel at equilibrium? There will be very little Bry and OCI. There will be very little Broci and Brci. XS ? Neither of the above is true What is the equilibrium constant for the following reaction? Round your answer to 3 significant digits. BrOCI()+BrCl() Br2(0)+OCI (0) What is the equilibrium constant for the following reaction? Round your answer to 3 significant digits. 3 Br2(0)+30C1(0) 3BrOCI(g)+3BrCl(a) KO

Answer 1

Griven reaction, Br₂ (2) + Och (2) Brou (2) + Brer (8) and the equilibrium constant for this reaction, K =999 Griven, 0.76 mol of Brou are y Bru in 44 L mol of Broc and oth mor and 6.76 mol 4 vessel. Now, from the balanced reaction we know, if one mole of Brol and one mole i Brel are keep in a reaction ressed, then they are in equilibrium with one mole of By and one mole of ou. - Samely, here if 0.76 mol of Broll and 0.76 mol af Bru are keep in 462 vessel, they obviously in equilibrium with 0.76 mol af Bry and 0.76 mol you. No one (both reactant and product) in very little amount. Ans. Neither of above is true from the given data we know, K= [Brou] [Bre ] = 999 - [Br] [ou] Now, here the reaction will be Brou (1) + Brel (2 ² Bra (8) +01 (2) se, equilibrium constant, x= [Br] [ Ouz] [Broa] [Bru] = /u [from equation no = /ggg = 100 x 10-3 ]

So, the equilibrium constant will be 1.000 10 -3 Griven reaction, Bry (2) + 3002(8) 7 3 Brou (8) + 3 Bra (8) So equilibrium constant & Brou (Brut [Brz] ³ [ou]? = (x3 [from equation no lo] = 9993 - 9.97X108 Hence, the equilibrium constant will be 9.97 x 108 WW
