Test yourself Answers:

9.1

i.       Why reversible reactions never complete?

Ans. In reversible reactions the products recombine to form reactants and this process keep on continuing. Therefore reversible reactions never go to completion.

ii.     What is static equilibrium, explain with an example?

Ans. Static equilibrium is a state in which the reaction ceases (stop) to proceed. This phenomena is usually applicable in physical phenomena not in chemistry.

For Example:

A hanging picture on wall never falls down because all the forces acting on it are equal and the net force is zero etc.

iii.    Why the amounts of reactants and products do not change in reversible reaction?

Ans. The amount of products and reactants do not change in reversible reaction because the amount of substance changing into reactants from products is equal to the amount of substance changing from reactants to products. Therefore the amount of products and reactants remain constant in reversible reaction.
