Assertion (A) : The equilibrium constant...

Assertion (A) : The equilibrium constant is fixed and characteristic for any given chemical reaction at a specified temperature.
Reason (R) : The composition of the final equilibrium mixture at a particular temperature depends upon the starting amount of reactants.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reasonb is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
The equilibrium constant is always fixed and is a characteristic of a reaction at specified temperature. It defines the composition of the final equilibrium mixture of that reaction, regardless of the starting amount of reactants and products.

The equilibrium constant in a reversible reaction at a given temperature which

Assertion: The equilibrium constant may show higher or lower values with increase in temperature. Reason: The change depends on the heat of reaction at equilibrium.

Assertion (A): The endothermic reactions are favoured at lower temperature and the exothermic reactions are favoured at higher temperature. Reason (R ) : when a system in equilibrium is disturbed by changing the temperature, it will tend to adjust itself so as to overcome the effect of the change.

Assertion (A) : The values of equilibrium constant of forward and backward reactions are same. Reason (R ) : Under particular set of conditions, the values of equilibrium constants of forward and backward reactions are reciprocal to each other.

Assertion (A ) : The value of equilibrium constant tells us about the extent to which the reactants are converted into the products before the equilibrium is attained at that given temperature. Reason (R ) : A small value of K means only small quantities of reactant have undergone change into the products.
