Learning Goal:
To determine equilibrium concentrations from initial conditions.
The reversible reaction
XY(aq)âX(aq)+Y(aq)
has a reaction quotient Qc defined as
Qc=[X][Y][XY]
Because the reaction is reversible, both the forward and reverse reactions will occur simultaneously. The reaction will eventually reach equilibrium, at which point the concentrations do not change, and Qc is equal to a constant known as Kc.
Part C
Based on a Kc value of 0.180 and the data table given, what are the equilibrium concentrations of XY, X, and Y, respectively?
Express the molar concentrations numerically.
