Why equilibrium state is attainable from either way ?
Why at equilibrium state r reaction mixture does not contain 50% amount of reactants and 50% amount of products?

answer:• Define chemical equilibrium in terms of a reversible reaction. (Understanding);

• Write both the forward and the reverse reaction and describe the macroscopic

characteristics of each. (Applying);

• Define Law of Mass Action. (Understanding);

• Derive an expression for the equilibrium constant and its units. (Applying);

• State the necessary condition for the equilibrium and the ways that equilibrium can be

recognized. (Understanding) and

• Write the equilibrium constant expression of a reaction.

Explanation:

you need to give more information

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
