For the given chemical equilibrium, which component will have maximum concentration?A(g) B(g) + 2C(g) + 3D(g); Kc = 10–6
Question
For the given chemical equilibrium, which component will have maximum concentration?
A(g) ⇌ B(g) + 2C(g) + 3D(g);
Kc = 10⁻⁶
Solution
The given chemical equilibrium is: A(g) ↔ B(g) + 2C(g) + 3D(g) with Kc = 10^-6.
The equilibrium constant expression for this reaction is: Kc = [B][C]^2[D]^3 / [A]
Given that Kc is very small (10^-6), this means that the reaction strongly favors the reactants. In other words, at equilibrium, the concentration of the reactants (A) is much higher than the concentration of the products (B, C, D).
Therefore, the component with the maximum concentration at equilibrium will be A(g).
