Initially, only A and B are present, each at 2.00 M . What is the final concentration of A once equilibrium is reached? What is the final concentration of D at equilibrium if the initial concentrations are [A] = 1.00M and [B] = 2.00 M?
The reversible chemical reaction A + B ↔ C + D has the following equilibrium constant: Kc = [C][D]/[A][B] = 4.7.
