Answer #1

a)

we are increasing concentration of a reactant

According to LeChattelier's Principle,

Adding reactant will shift reaction towards product side

Equilibrium moves to right

b)

we are decreasing concentration of a product

According to LeChattelier's Principle,

Removing product will shift reaction towards product side

Equilibrium moves to right

c)

we are decreasing concentration of a reactant

According to LeChattelier's Principle,

Removing reactant will shift reaction towards reactant side

Equilibrium moves to left

So, more than one correct response

Answer: d
