There will be a shift towards the reactants

Rus_ich [418]3 years ago

Answer:

As temperature is decreased the reaction will shift towards the reactants i.e. it will favour the formation of PCl5

Explanation:

According to Le Chatelier's principle, when a reaction at equilibrium is subject to a change in temperature, pressure, concentration etc then the equilibrium will shift in a direction so as to undo the effect of the induced change.

The given reaction is:

PCl5(g) + heat ↔ PCl3(g) + Cl2(g)

This reaction is endothermic i.e. heat is absorbed by the reactants. When the temperature is decreased, this would imply that heat is being removed from the system. Therefore, as per Le Chatelier's principle the equilibrium will shift in a direction that would favor more input of heat i.e. it will shift towards the reactants.

How many atoms are there in 24 moles of Fe?

Semenov [28]

Answer: There are $145 \times 10^{23}$ atoms in 24 moles of Fe.

Explanation:

According to the mole concept, 1 mole of a substance contains $6.022 \times 10^{23}$ atoms.

Therefore, atoms present in 24 moles of Fe are calculated as follows.

$24 mol \times 6.022 \times 10^{23} atoms/mol\\= 144.52 \times 10^{23} atoms\\or, 145 \times 10^{23} atoms$

Thus, we can conclude that there are $145 \times 10^{23}$ atoms in 24 moles of Fe.

CH3CO2H(aq) + H2O(l) ⇄ CH3CO2-(aq) + H3O+(l)

Evgen [1.6K]

Correct Answer: Option C: The equilibrium position will shift to the right toward the products.

Reason:
1) This problem is based on Le Chatelier's principle. It is stated as 'any changes in the temperature, volume, or concentration of a system will result in predictable and opposing changes in the system in order minimize this change and achieve a new equilibrium state.'

2) In present case, the reaction involved is:
 CH3CO2H(aq) + H2O(l) ⇄ CH3CO2-(aq) + H3O+(l)
Hence, when the concentration of acetic acid (reactant) is increased, the equilibrium will shift to right to minimize the effect of change in concentration of reactant.

What is the equation between aqueous sodium carbonate and dilute hydrochloric acid

deff fn [24]

Answer:

When solutions of sodium carbonate and hydrochloric acid are mixed, the equation for the hypothetical double displacement reaction is: Na2CO3 + 2 HCl → 2 NaCl + H2CO3 Bubbles of a colorless gas are evolved when these solutions are mixed.

I am having trouble converting :(

Elza [17]

Answer:

For the first question, to determine the total number of molecules of nitrogen dioxide, first make use of the molar mass of the nonpolar compound and then use that to find the total number of moles and then subsequently after make use of the ratio for the Avogadro's number to determine the total number of molecules of this compound.

For the final question, do the inverse, where we make use of the molecules of the compound and then use Avogadro's number to determine the moles of the compound and then use the same molar mass of the compound to determine the grams of the Nitrogen Dioxide.
