Suppose the reaction system below has already reached equilibrium. Predict the effect that each of the following changes will ha
WARRIOR [948]

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

  • On removal of reactant from equilibrium reaction ,shifts the equilibrium in backward direction.
  • On addition of reactant from equilibrium reaction ,shifts the equilibrium in forward direction.
  • On removal of product from equilibrium reaction, shifts the equilibrium in forward direction.
  • On addition of product from equilibrium reaction, shifts the equilibrium in backward direction.

UO_2(s) + 4 HF(g)\rightleftharpoons UF_4(g) + 2 H_2O(g)

1. Water vapor is removed

On removal of water vapor from equilibrium will decrease the product which will lead to moving forward of an equilibrium that is equilibrium will shift to right direction.

2. UF_4(g) is added

On addition of UF_4(g) from equilibrium will increase the reactant which will lead to moving forward of an equilibrium that is equilibrium will shift to right direction.

3.The reaction is done in a glass reaction vessel. HF(g) attacks and reacts with the glass

Due to reaction of HF with glass will result in decrease in amount of HF present at equilibrium. So, order to counter this equilibrium will shift in backward direction or in left direction.

4. If the reaction is endothermic, and you want to make the equilibrium shift to the right to maximize the products, would you heat or cool the reaction vessel.

I endothermic reaction , heat is added to the reaction for which we can treat heat as a reactant.Now, we want to shift the equilibrium to right which means in the forward direction.

And this can be done by increasing the reactant amount, here by adding more heat to the equilibrium will shift the reaction to the right side.

So, for increasing heat we will heat the reaction vessel.

What would be the mass of 4.56x10²³ water molecules
kifflom [539]
Every time you see molecules, atoms, & particles think of avagadros #. (6.022 x 10^23)

Answer: 13.6 grams of H2O

Solution: (4.56x10^23) x (1 mol H2O/6.022x10^23) x (18 grams H2O/1 mol H2O) = 13.6 grams of H2O

Using dimensional analysis above makes these types of problems easy.
