H2(g), I2(g), and HI(g) are at equilibrium at a different temperature in a different vessel. (c) When the temperature in the vessel is decreased, does the equilibrium shift to the right, favoring the product, or to the left, favoring the reactants? Justify your answer. Rigid vessel

Answer 1

Answer:

The reaction will shift rightwards favoring the product.

Explanation:

Hello,

In this case, considering the chemical reaction to be:

[tex]H_2(g)+I_2(g)\rightleftharpoons 2HI(g) ;\Delta H^o rxn=-9.4kJ/mol;Kc=49[/tex]

We notice that the sign of the change in the enthalpy of the reaction is negative, therefore this an exothermic chemical reaction in which the heat is a product as the reaction vessel heats up as the reaction undergoes. In such a way, by decreasing the temperature we are removing heat and by means of the Le Chatelier's principle, when removing a product, the reaction will shift rightwards favoring the product, HI.

Best regards.

Answer 2

Answer:

the balance will shift to the right, favoring the products. More HI will be formed.

Explanation:

Step 1: Data given

H2(g), I2(g), and HI(g) are at equilibrium at a different temperature in a different vessel.

Step 2: The balanced equation

H2(g) + I2(g) ⇆ 2HI(g)

Step 3:

If the temperature is increased, the system will release less heat as reaction.

Since formation of HI is exothermic

When the temperature drops, the system will produce more heat. With the result, the balance will shift to the right, favoring the products. More HI will be formed.

Final answer:

In the reaction Li2O + MgCl2 → 2LiCl + MgO, the second reactant is magnesium chloride (MgCl2), the first product is lithium chloride (LiCl), and there are 2 lithium atoms on the product side.

Explanation:

The chemical reaction you are referring to is Li2O + MgCl2 → 2LiCl + MgO. In compliance with your question:

The second reactant in the equation is magnesium chloride (MgCl2).The first product of this reaction is lithium chloride (LiCl).On the product side, there are 2 lithium (Li) atoms, as indicated by the coefficient in front of LiCl.

It's essential to note that in a balanced chemical equation, the number of atoms of each element must be the same on both the reactants and the products side.

Is it possible for a heat transfer system to involve both internal and external convection simultaneously?

Answers

Answer:

When the fluid is forced to flow over a surface it is external forced convection. When the fluid is forced to flow in a tube it is Internal forced convection. It is possible to have both Internal and external convection simultaneously as is case of pipe transporting a fluid in a windy area.
