Consider the following reaction. It is occuring in a closed system and it is currently at equilibrium:
2H2O(g) + Heat ↔ 2H2(g) + O2(g) |
Label each of the following statements with is effect on the
reaction
shift towards products or shift towards reactants or no change:
Removing oxygen gas.
shift towards products or shift towards reactants or no
change: Cooling the reaction vessel.
shift towards products or shift towards reactants or no
change: Removing water vapor from the vessel.
shift towards products or shift towards reactants or no
change: Increase the size of the vessel.
shift towards products or shift towards reactants or no
change: Decrease the pressure on the reaction vessel
1)
Removing product will shift the reaction in the direction of
product as per Le chatelier Principle
So, Equilibrium moves to product side
Answer: shift towards products
2)
Decreasing Temperature will shift the reaction in a direction which
release heat as per Le chatelier Principle
Forward reaction is endothermic in nature
hence, backward reaction will be favoured
So, Equilibrium moves to reactant side
Answer: shift towards reactants
3)
Removing reactant will shift the reaction in the direction of
reactant as per Le chatelier Principle
So, Equilibrium moves to reactant side
Answer: shift towards reactants
4)
Increasing volume will decrease the pressure which in turn shift
the reaction in a direction which have greater gaseous molecules as
per Le chatelier Principle
Here product has more gaseous molecule
So equilibrium will move to right
So, Equilibrium moves to product side
Answer: shift towards products
5)
Decrease the pressure will shift the reaction in a direction which
have greater gaseous molecules as per Le chatelier Principle
Here product has more gaseous molecule
So equilibrium will move to right
So, Equilibrium moves to product side
Answer: shift towards products
