Question

Does law of mass action apply on the above reaction​

Answer 1

Yes, the Law of mass action applies to the given reaction.

• The given compound is hexaaquacobalt ion which is reacting with two moles of chloride ion.
• The reaction is forming one mole of hexaaquacobalt (II) chloride complex.
• The number of particles of cobalt, water and chlorine is the same on both sides and thus the law of mass action applies to the reaction.
• Cobalt is one on both sides, water molecules are six on both sides and chlorine atoms are two on both sides.
