Answer:
B. 091
Explanation:
When we add these two equilbria, the equilibrium constant for the resultant equilibrium is the product of the first two.
Notice that when we add the first two reactions in this question, we obtain the equilibrium for which we are seeking its equilibrium constant. Therefore,
A(g) + B(g) ? AB(g) Kc₁ = [AB] / [A][B]
+
AB(g) + A(g) ? A2B(g) Kc₂ = [A₂B] /[ AB][A]
_________________________________
2 A(g) + B(g) ⇄ A₂B(g) Kc₃ = [A₂B] / [A]²[B]
Kc₁Kc₂ = [AB] / [A][B] x [A₂B] / [AB][A] = [A₂B] / [A]²[B]
Thus,
Kc₃ = 0.24 x 3.8 = 0.91
This procedure is not limited to two reaction, it could done for more than two, as long as the desired equilibrium is the desired one.
The study of a living being is called biology.
The correct answer is B that is 0.91.
When we add these two equilibria, the equilibrium constant for the resultant equilibrium is the product of the first two.
All the data is given in the question. We have to substitute all the reactions in the question and find the correct answer.
The equation is mentioned in the question. after solving it the PKA value of AB is 0.91.
[tex]K_{C3} = 0.24 *3.8 = 0.91[/tex]
This procedure is not limited to two reactions, it could be done for more than two, as long as the desired equilibrium is the desired one.
Hence, the correct answer is B that is 0.91.
