The equilibrium constant, Kp, for the reaction H2(g) + I2(g) → 2HI(g) is 55.2 at 425°C. A rigid cylinder at that temperature con
Fiesta28 [93]

<u>Answer:</u> No, the reverse reaction must proceed to establish equilibrium.

<u>Explanation:</u>

K_p is the constant of a certain reaction at equilibrium while Q_p is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

H_2(g)+I_2(g)\rightleftharpoons 2HI(g)

The expression of Q_p for above equation follows:

Q_p=\frac{(p_{HI})^2}{p_{H_2}\times p_{I_2}}

We are given:

p_{HI}=1.055atm\\p_{H_2}=0.127atm\\p_{I_2}=0.134atm

Putting values in above equation, we get:

Q_p=\frac{(1.055)^2}{0.127\times 0.134}=65.41

We are given:

K_p=55.2

There are 3 conditions:

  • When K_{p}>Q_p; the reaction is product favored.
  • When K_{p}; the reaction is reactant favored.
  • When K_{p}=Q_p; the reaction is in equilibrium.

As, Q_p>K_p, the reaction will be favoring reactant side or the reaction must proceed in the reverse direction.

Hence, no, the reverse reaction must proceed to establish equilibrium.

What volume of 9 M sodium hydroxide is required to make 500 mL of 0.1 M sodium hydroxide?
MArishka [77]

Answer:

6mL

Explanation:

V₁M₁ = V₂M₂

V₁ =  V₂M₂/M₁

V₁ = (500)(0.1)/(9)

V₁ = 5.56mL ≈ 6mL

A Group VIIA atom combines with a Group IA atom. The bond formed between them will most likely be:
ad-work [718]

Answer: The correct answer is option B.

Explanation:

  • Ionic bond is formed when there is complete transfer of electrons from one element to another.
  • Covalent bond is formed by the sharing of electrons between two elements.
  • Metallic bond is formed when two metals combine together.

Electronic Configuration of Group VII-A : ns^2np^5

This group require 1 electron to attain stable electronic configuration.

Electronic configuration of Group I-A : ns^1

This group will loose 1 electron to attain stable electronic configuration.

So, there will be complete transfer of electron from Group VII-A to Group I-A and hence, will form ionic bond between them.

Hence, the correct option is B.
