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.

Which of the following is NOT part of the kinetic molecular theory of gases?

kondaur [170]

A. There is very little empty space in a gas in not part of the kinetic molecular theory of gases.

Explanation:

The kinetic molecular theory of gases follows following points:

Kinetic energy does not change or get dissipated when gas molecules collide with each other. No attraction or repulsion between gas particles is observed. Particles of gas are moving randomly in all directions. Temperature increase cause the rapid movement of gas particles.The gas particles are placed very far from each other as compared to liquid.

The empty space in a gas is large because gas gets compressed in the small volume of the container also.

Part A Which of the following statements about chemical formulas is FALSE? Which of the following statements about chemical form

statuscvo [17]

Answer: Option (a) is the correct answer.

Explanation:

Subscript present in chemical formula of a compound represents the number of atoms of the element actually present in it.

For example, in $C_{7}H_{7}NO_{2}$ the subscripts present in it are 7, 7, 1, and 2.

A subscript is not responsible for determining the relative mass of each type of an atom because a subscript simply represents the number of atoms of each type of an element participating or combining with other atoms of a compound.

Thus, we can conclude that the statement subscripts represent the relative mass of each type of atom in the compound, is false.
