Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Adding inert gas to dissociation equilibrium of N2O4 at constant pressure and temperature increases the dissociation.
When inert gas is added at constant pressure, the partial pressure of gaseous species decreases.
Molar concentration of the reactants and products decreases. The
equilibrium will shift in forward direction so that more and more of
N2O4 dissociates to form NO2. The reaction proceeds in the
forward direction with increase in the number of moles of gaseous
species.
Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
