A. The reaction would remain in equilibrium

Further explanation

Given

Reaction

H₂ + I₂ ⇔ 2HI

Required

the effect of pressure changes

Solution

In the equilibrium system :

Reaction = - action  

⇒shift the reaction to the right or left.  

The pressure usually affects the gas equilibrium system(only count the number of moles of gases)

The addition of pressure, the reaction will shift towards a smaller reaction coefficient  ((the fewest moles of gas  )

Reaction

H₂ + I₂ ⇔ 2HI

The reactant side of the equation has 2 moles of a gas(1 mole H₂ and 1 mole  I₂) ; the product side has 2 moles HI

So the total number of moles from both sides is the same(2 moles) so that the change in volume (pressure) does not change the direction of equilibrium⇒No shift will occur
