FREE Expert Solution

We’re being asked to determine the equilibrium concentrationof C given the following equilibrium reaction:

2 A(aq) + B(aq) ⇌ 2 C(aq)Kc = 1.5x10-8


We know that the initial amount of A and B is 0.1 M. From this, we can construct an ICE table:



Kc is the equilibrium expression of the concentrations in the reaction. The general form of an equilibrium expression is:
