Explain the characteristics of the chemical equilibrium
Answers
Explanation:
Characteristics of chemical equilibrium - definition
At a given temperature, the measurable properties like pressure, concentration, density or colour remain constant in chemical equilibrium. Chemical equilibrium can be attained from either side (forward and backward reactions).
Answer:
Actually at equilibrium the rate of forward reaction becomes equal to the rate of backward reaction, so that there is no net change in the concentration of various species. In other words we can say that equilibrium state is a dynamic balance between the forward and backward reaction. This can be illustrated by considering the reaction between hydrogen and iodine to form hydrogen iodide.
When hydrogen and iodine are taken in a closed vessel maintained at 717k hydrogen molecules combine with iodine to form hydrogen iodide.
H2+I2←2HI
The molecules of HI will also start to dissociate into H2 I2.
