Physical and chemical equilibrium can respond to a change in their pressure, temperature, and concentration of reactants and products. To describe the change in the equilibrium we have a principle named Le Chatelier principle. According to this principle, even if we make some changes in equilibrium, then also the system even re-establishes the equilibrium by undoing the effect.
Consider the following equilibrium:
`2NO_(2) hArr 2NO_(3), DeltaH=-ve`,
If `O_(2)` is added and volume of the reaction vessel is reduced, the equilibrium

A. Shift in the product side
B. Shifts in the reactant side
C. Cannot be predicted
D. Remains unchanged

Explanation

Shift in product side.
