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

<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.
