Consider with and with . Ten mol of C is taken in a 1 L vessel. Calculate the equilibrium concentration of B. If it is M, enter .
Answer:
5.00
Solution:
Let [A]=t and [B]=2t from dissociation of C. Since D⇌C has K=1, [D]=[C]=(10-t)/2. Then 10¹⁶=[C]/([A][B]²)=(10-t)/(8t³). With t≪10, [C]≈5 M and t≈[5/(4×10¹⁶)]^(1/3)=5×10⁻⁶ M. Thus [B]≈10⁻⁵ M and the requested exponent is 5.
