Question

(b) (4 pts.) The following pictures represent the equilibrium state for four different reactions of the type A2 + X 2 2 AX (X=B, C, D, E) A atoms are unshaded. X atoms are shaded. go 8 8 8.00 8 19 A, + B 2AB A, + C, A 2AC A, + D2 2AD A, + E 2AE Which reaction has the largest equilibrium constant? Explain your reasoning.

Answer 1

08. Equilibrium conut you a particolar Equilibrium mxn is the malio lonin product to conch reactant of % of . ex - A2 + B2 BAB keq [AB] [Az] [B2 will be the It show's that higher the conen equilibrium cónstt. of product higher Given : A2+ X2 → 2AX keq = [axy2 [AZ] [X2 A →→ X So, Az → oo o X2 АХ so higher the Ax moleluses in Beaker higher will be equilibrium const 8 A, + B, 2AB A, + C, A 2AC A, + D 2AD A, + E, 2AE For Reaction 1 : A2 + B2 i 2AB 1 of From Figure No. No. No Az molecule = B2 molecule = AB molecule = 8 1 of of 2 ویے keq = [MB] 64 64 [A] [B2 1

Similarly we can find keq for each B, C,D 4 СА,ОСc2] Ryn/2 keq = [ac]2 42 3х3 Вxn3 4 kes с 1 - — [Apj- [ATLD21 3х4 3х9 3 . Rxn 4 keq = =[AE]² САjГЕ2] г 62- 2 x 2. - 36 = 9 4 keg of Rxn 1 in largest.
