Condider the equilibrium:

2H^+1 (aq) + 2CrO4^-2 (aq) ---> H2O + Cr2O7^-2 (aq)

What directino would the equilibrium shift in the following cases?

The [H^+1] is increased.
The [H2O] is increased.
The [H20] is decreased.
More NaOH is added (uses up H^+).

Homework Answers

Answer #1

1)

we are adding a reactant

According to Le Chatelier's Principle,

Adding reactant will shift reaction towards product side

Answer: Equilibrium moves to product side

2)

Adding solid or liquid doesn't affect equilibrium

Answer: No effect on equilibrium

3)

Removing solid or liquid doesn't affect equilibrium

Answer: No effect on equilibrium

4)

we are removing a reactant as OH- will consume H+

According to Le Chatelier's Principle,

Removing reactant will shift reaction towards reactant side

Answer: Equilibrium moves to reactant side
