1it depends on the value of change in the number of moles of the chemical reaction.....
what is the effect of adding inert gas at constant pressure to a system?

39Inert gas doesn't react with the contents of the system. So it's a volume increase?
1it causes the system to move in direction of larger no of gaseous molecules bcoz in this process , the volume is allowed to increase ,so, the partial pressures of all gases would be decreased resulting in a shift towards the side with the greater number of moles of gas.

1addition of an inert gas only increases the volume ....
so Δn>0 then in the expression of equilibrium constant volume appears in the denominator and therefore eq constant decreases and so forward reaction is favoured ....
and similarly when Δn<0 then volume is in the numerator and so increase in volume increases the eq constant and so backward reaction is favoured ....
when Δn=0 there is no effect of adittion of inert gas .......
