WHAT IS EQUILIBIRUM IN CHEMISTRY . WHAT IS DIFFER IN MEDICINE AND DRUG IN CHEMISTRY

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction.
A drug is a chemical substance that takes control of your body or mind depending on its own inherent nature. For example – when you take a sleeping pill, it puts you to sleep no matter how much you want to be awake! It rules over your body & mind. You can repeat this exercise many times – and you will experience the same every time.
Medicine is the substance that helps restore “normalcy” to your body & mind. Normalcy is actually nothing but your volitional control over your own body & mind. Hence its action can be seen to be the exact opposite of the drug. The proof of that helpful action of medicine is - that you will never require a medicine compulsively, threatening discomfort and danger when not taken on time
