What is the effect of the temperature on the no of moles in an equilibrium system?
Well, your equation contains the same number of moles either side, so temperature does not matter.

But if the equation had different moles on either side, it should be given if the reaction is endothermic or exothermic.

For eg- if a reaction is exothermic and the temperature is increased, then according to Le Chatelier's principle, the reaction should go in the backward direction (To compensate for the increase in temperature).
So, if the reactant side has more moles than product side, the number of moles will be increased. You can apply similar logic if the reaction is endothermic.
