Assertion : Adding inert gas to dissocia...

Assertion : Adding inert gas to dissociation equilibrium of `N_(2)O_(4)` at constant pressure and temperature increases the dissociation.
Reason : Molar concentration of the reactants and products decrease.

A

Statement 1 is True, statement 2 is True, Statement 2 is correct explanation for Statement 1.

B

Statement 1 is True, statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement 1 is True, statement 2 is false.

D

Statement 1 is False, Statement 2 is True.

Text Solution

Verified by Experts

The correct Answer is:
A
To keep the pressure constant volume would increase. As a result molar concentration of each reactant and product will decrease. For `N_(2)O_(4) hArr 2NO_(2), K = ([NO_(2)]^(2))/([N_(2)O_(4)])`
To keep K constant , `N_(2)O_(4)` should decreases more.

Statement 1: In the dissociation of PCl_(5) at constant pressure and temperature addition of helium at equilibrium increases the dissociation of PCl_(5) . Statement 2: Helium reacts with Cl_(2) and hence shifts the equilibrium in forward direction.

Assertion : The equilibrium constant for the reverse reaction is equal to the inverse of the equilibrium constant for the forward reaction. Reason The value ofequilibrium constant is independent of initial concentrations of the reactants and products.

    Statement 1 : The equilibrium constant for the reverse reaction is equal to the inverse of the equilibrium constant for the forward reaction. Statement 2: The value of equilibrium constant is independent of initial concentration of the reactants and products.

    Assertion :The order of a reaction maybe negative. Reason:In some cases, the rate of reaction decreases as the concentration of the reactant increases.

    Assertion : For the physical equilibrium, H_(2)O(s) iff H_(2)O(l) , increasing the temperature and increasing the pressure result in the formation of more water. Reason : The shift in the forward direction is both endothermic and accompanied by an increase in volume.

    Assertion : Addition of an inert gas at constant pressure to dissociation equilibrium of PCl _(5) hArr PCl _(3) + Cl _(2) favours forward reaction. Reason: K _(e) = (alpha ^(2))/( V (1- alpha)) for the dissociation equilibrium of PCI_(5) where a is degree of dissociation of PCl _(3).

    Assertion : Order of a reaction with respect to any reactant can be zero, positive, negative or fractional. Reason: Rate of a reaction cannot decrease with increase in concentration of a reactant or a product.
