Adsorption from solution. The process of adsorption can take place from solutions also. 1) When solution of acetic acid in water is shaken with charcoal, a part of the acid is adsorbed by charcoal and therefore, the concentration of acetic acid decreases in the solution. 2) When magnesium is precipitated as magnesium hydroxide, in the presence ...

We can see that the second reaction is essentially the first reaction repeated 5 times. Therefore, the equilibrium constant for the second reaction (Kc2) is the equilibrium constant for the first reaction (Kc1) raised to the power of 5. In mathematical terms: Kc2 = (Kc1)^5. Substituting the given value of Kc1 into the equation: Kc2 = (0.28)^5
