i think time. .........

Changes in time do not shift the equilibrium of a chemical reaction.

Chemical equilibrium is the state where no net change in the quantity of reactants as well as products occurs during a reversible chemical reaction. A reversible chemical reaction occurs when the products react with the original reactants as soon as they are generated.

A chemical reaction occurs when one or more compounds, known as reactants, are changed into one or more distinct substances, known as products. Chemical elements or compounds are examples of substances. A chemical reaction organizes the constituent atoms of both the reactants to produce various products.

N2(g) + 3H2(g) → 2NH3(g)

20ml of nitrogen

the volume of produced NH3

So, 1 volume of nitrogen gas reacts with 3 volumes of hydrogen gas to produce 2 volumes of ammonia gas.

For this gaseous reaction in which all the reactants and products are gases we could write a chemical equation:

1 volume N2(g) + 3 volumes H2(g) → 2 volumes NH3(g)

1 volume of N2 is 20 ml so 2 volume of NH3 will be 40 ml .

Then , 20 ml N2 will give 40 ml of NH3

= 40 ml

The molarity of the methanol solution produced at the given number of moles and volume is 0.75 M.

The molarity of the methanol is determined from the ratio of the number of moles of the methanol to the volume of the methanol.

The molarity of the methanol is calculated as follows;

Molarity = moles/volume

moles = 0.2 L x 3 M = 0.6 mole

Molarity = 0.6 mol/0.8 L

Molarity = 0.75 M

Thus, the molarity of the methanol solution produced at the given number of moles and volume is 0.75 M.

Answer:

If one increases the temperature of a gas in a sealed, rigid container, the density of gas will not change.

The key to this answer lays in the ideal gas equation:

        pV = nRT

Thus, one can write:  n = (m)/(M)where m is the mass of the gas and M is the molar mass of a gas.  

         pV = (m)/(M) RT

Hence, if one decides to divide the entire equation with volume, V, one may write:

        p = (m)/(VM) RT

ρ = (m)/(V), where ρ is density

        p = (ρ)/(M) RT

If one increases the temperature, in order to keep balance, the pressure will be increased, also.  Container is rigid, so that means the volume is constant.

However, this will not affect the density because there is no difference in volume (V = const.) or the amount of gas (n = const).

If one had a container with a piston, yet, constant pressure, the change of the temperature will impact the density.

Chemical equilibrium is a dynamic equilibrium that is affected by changes in temperature, concentration and pressure

Chemical equilibrium is a dynamic state in a chemical reaction in which the rate of forward reaction is equal to the rate of backward reaction.

For a reaction in equilibrium, the following factors affect equilibrium:

The principle of chemical equilibrium states that in an isolated system in equilibrium, equilibrium will shift to annul any constraint applied in the system.

Therefore, chemical equilibrium is dynamic and is affected by temperature, concentration and pressure.

Explanation:

In chemsitry, the horizontal columns are known as periods and the vertical columns are known as groups.

No, a pressure cannot change shift the equilibrium position in every reversible reaction.

If the pressure increases, the position of equilibrium shift in the direction with the small amount of molecules. This decreases the effect of the change. When the reaction will shift towards the products that means the reaction favor forward.

From the above conclusion we can say that a pressure cannot change the shift of equilibrium position in every reversible reaction.

The effects of each of the following on the equilibrium system in the question are as follows :

A) Addition of Cl₂ ; equilibrium shifts to reverse

B) Removal of HCl ; equilibrium shifts to the reverse

C) Increased pressure ; neither

D) Decresed temperture ; neither

E) Removal of H₂ ; Forward

F) Decreased pressure : neither

G) Addition of catalyst : Forward

H) Increased temperature : Forward

I) Decresed system volume : Neither

The change in volume and pressure in an equilbrium system with equal number of gaseous molecules of reactants and products will not have an effect on the direction of shift of the equilibrium system. But the change in temperature, increase or decrease of reactants and products  will have an effect on the direction of the equilibrium shift of the system.

Hence we can conclude that the effects of the following on the equilibrium system is as listed above.
