According to le chatelier’s principle, if products are removed from a system at equilibrium, the reaction will

The reaction will move in forward direction.

Explanation:

Le-Chatelier's principle states that , "If a system at equilibrium is subjected to a change (in pressure, temperature or concentration of reactants/products), the system will behave in such a way as to oppose the change i.e, it will either move in forward or backward direction."

If the products are removed from a system at equilibrium then it will tend to produce more products so the reaction will shift to forward direction.

im sorry i dont know

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
