Which of the following statements is correct?A large Keq value indicates that products are favored.
A small Keq value indicates that the reverse reaction will occur very quickly.
A large Keq value indicates that reactants are favored.
A small Keq value indicates that products are favored.

Answers

Answer 1
Answer:

The statements that are correct are ‘A large Keq value indicates that products are favored.’ And ‘A small Keq value indicates that the reverse reaction will occur very quickly.’ Having large Keq means that the concentration of the product is greater than the reactants and so products are favored. Having small Keq means that the concentration of the reactants is greater than the product.
Answer 2
Answer:

A large Keq value indicates that products are favored.

Consider this equilibrium:N2(g) + 3H2(g) 2NH3(g) + energy.

Certain conditions provide less than 10% yield of NH3 at equilibrium. Which statement describes this equilibrium?

Answers

This is the complete answer, including the set of answer choices:

Certain conditions provide less than 10% yield of NH3 at equilibrium. Which statement describes this equilibrium?

A. The Keq is large and products are favored.
B. The Keq is small and products are favored.
C. The Keq is large and reactants are favored.
D. The Keqis small and reactants are favored.
E. The conditions of the reaction must be known to answer the question


To answer you must know that the equilibrium yield is the quantity of product obtained.

In this case it is 10% of NH3.

That means that the equilibrium is more favorable to the reactants.

Given that Ke relates the concentration of products / concentration of reactants, the answer is the Ke is small and reactants are favored

Final answer:

This equilibrium has a low yield of NH3 and can be improved by adjusting the conditions and using the principles of Le Chatelier.

Explanation:

This equilibrium can be described as an equilibrium with a low yield of NH3. The fact that less than 10% yield of NH3 is obtained suggests that the forward reaction (N2(g) + 3H2(g) -> 2NH3(g) + energy) is not favored under the given conditions. To increase the yield of NH3, the conditions can be adjusted to shift the equilibrium towards the product side.

The Le Chatelier's principle can be applied to achieve a higher yield of NH3. One possible way is to increase the concentration of the reactants (N2 and H2) or decrease the concentration of the product (NH3). Another way is to increase the temperature, as this reaction is exothermic. By increasing the temperature, the equilibrium will shift in the reverse direction to consume the excess energy.

In summary, this equilibrium is characterized by a low yield of NH3, which can be improved by adjusting the conditions and using the principles of Le Chatelier.

Why is there no overall electrical charge on an aluminium atom?

Answers

The atoms always have an equal amount of protons and neutrons so lets say if one had 10 positive then it would have 10 negatives making it neutral.

How many grams is 1.2 moles of Neon?

Answers

Mass of Neon : = 24.21564 g

Further explanation

Given

1.2 moles of Neon

Required

mass of Neon

Solution

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

Mol = mass : Molar mass

so mass of Neon(MM=20,1797 g/mol) :

= mol x MM

= 1.2 x 20,1797

= 24.21564 g
