WebJan 30, 2024 · Kc is an equilibrium constant in terms of molar concentrations and is usually defined as: Kc = [C]c[D]d [A]a[B]b in the general reaction, aA + bB ⇌ cC + dD If a large Kc is formed then there are more products formed. Inversely, a small Kc indicates that the reaction favors the reactants. WebAt equilibrium the concentration of I 2 is 6.61 × 10 −4 M so that. The ICE table may now be updated with numerical values for all its concentrations: Finally, substitute the equilibrium concentrations into the K expression and solve: = 3.39 × 10 −4 M ( 6.61 × 10 −4 M) ( 6.61 × 10 −4 M) = 776.
