what are the properties of chemical equilibrium

Equilibrium is a stage when rate of forward and backward reaction becomes equal. In chemical equilibrium the rate at which the amount of reactant converted to product is equal to rate of conversion of product to reactant. 

At the state of equilibrium..

1. The concentrations of all the reactant and produces becomes constant.

2.. Temperature, pressure, heat change and all the other measurable quantities becomes constant

3. It is dynamic and reversible.

The graph of the chemical equilibrium can be represented as:
