Consider the following reaction: CO(g)+2H2(g)⇌CH3OH(g). The reaction between CO and H2 is carried out at a specific temperature with initial concentrations of CO = 0.29 M and H2 = 0.51 M. At equilibrium, the concentration of CH3OH is 0.14 M. Find the equilibrium constant at this temperature.

Answers

Answer 1
Answer:

Answer:

please check image and explanation

Explanation:

First write the balance chemical reaction

CO(g)+2H2(g)⇌CH3OH(g)

To find out the equilibrium constant first need to find the concentration of each entities at equilibrium.

A weather balloon at Earth’s surface has a volume of 3.9 L at 299 K and 763 mmHg. If the balloon is released and the volume reaches 4.13 L at 720 mmHg, what is the temperature? Answer in units of K.

Answers

Combined Gas Laws

Given: V1= 3.9L    V2= 4.13L   T1= 299K   P1=763mmHg   P2=720mmHg

Unknown: T2=?

Formula: T2=T1P2V2 / P1V1

Solution: T2= (299K)(720mmHg)(4.13L) / (763mmHg)(3.9L)
                   = 889,106.4 / 2975.7

Answer: T2=298.8K

Answers

All the following are examples of minerals, except timber.

The correct option is d, timber.

What are minerals?

Minerals are solid chemical compounds that have fixed or definite chemical compositions.

Some minerals are calcium, phosphorus, bauxite, iron etc.

Our body needs a very little amount of minerals for the boy's growth.

Timber is wood, which is not a mineral.

Thus, the correct option is d. timber.

Explanation:

Given the system at equilibrium:2POCl3(g) + energy <==> 2PCl3(g) + O2(g)
Which changes occur when O2(g) is added tothis system?
(1) The equilibrium shifts to the right and the concentration of PCl3(g) increases.
(2) The equilibrium shifts to the right and the concentration of PCl3(g) decreases.
(3) The equilibrium shifts to the left and the concentration of PCl3(g) increases.
(4) The equilibrium shifts to the left and the concentration of PCl3(g) decreases.

Answers

Given the data from the question, the correct answer to the question is:

The equilibrium shifts to the left and the concentration of PCl₃(g) decreases. (Option 4)

What is chemical equilibrium?

This is simply defined as a state in a chemical system where there is no observable change in the properties of the system with time.

A French scientist postulated a principle which helps us to understand a chemical system in equilibrium.

The principle states as follow:

  • If a an external constraint such as change in temperature, pressure or concentration is imposed on a system in equilibrium, the equilibrium will shift so as to neutralize the effect.

How to determine the position of equilibrium constant

Considering the question given above, we are concerned with O₂ (i.e concentration) being added to the reaction

2POCl₃(g) + energy <=> 2PCl₃(g) + O₂(g)

According to the principle given above, if more O₂ is added, then, PCl₃ and O₂ will react to produce more POCl₃. Thus, the equilibrium will shift to the left and also PCl₃ will reduce.
