In the 2nd case given below, it says that if at constant pressure a noble gas is added to a reaction at equilibrium it's volume increases,but here the increase in volume is due to addition of noble gas which occupies the extra volume and there is no contribution of the reactants and products of the reaction in the increment of volume .Then why does the equilibrium of the reaction gets disturbed due to addition of noble gas?

At constant volume, net conditions of reaction is constant therefore there is no affect of addition of noble gas on reaction.
Addition of noble gas at constant pressure can lead to change in volume therefore, the reaction moves Towards the side where there are more number of gaseous molecules
