Which will not appear in the equilibrium constant expression for the reaction below?

Chemistry
1 answer:
n200080 [17]3 years ago
5 0

Answer:

[C] carbon solid

Explanation:

Pure solids and liquids are never included in the equilibrium constant expression because they do not affect the reactant amount at equilibrium in the reaction, thus since your equation has [C] as solid it will not be part of the equlibrium equation.

Suppose that 2.14 grams of H2SO4 is mixed with enough water to make 225 mL of solution. Determine the Molarity (M) of the soluti
Alik [6]

Answer:

0.0970 M

Explanation:

Remember this equation:

mol/M x V

Convert it so that you can get M.

M=mol/V

Convert the 2.14 grams of H2SO4 into mols

=0.0218

Convert mL to L

225/1000

=0.225

Plug it in.

0.0218/0.225

=0.0970 M

Which of the following statements is TRUE?
borishaifa [10]

Answer:

Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction:

Explanation:

Reaction quotient is the ratio of product of concentrations of products to product of concentrations of reactants at any time.

The same ratio at equilibrium (when rate of forward reaction becomes equal to rate of backward reaction) is equilibrium constant.

when Q < Kc, a forward reaction is favored.

When when Q > Kc, a backward or reverse reaction is favored

So the first statement that

a) A reaction quotient (Q) larger than the equilibrium constant (K) means that the reaction will favor the production of more products: false

b) No the rate of forward and backward reaction are equal.

c) c. Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction: True

d) Dynamic equilibrium indicates that the amount of reactants and products are equal: This could be static equilibrium but not dynamic.

zhuklara [117]

Answer:

The statements are definitions to chromatography terms which have been highlighted below.

Explanation:

Match the chromatography term with its definition.

Volumetric Flow Rate = The volume of solvent traveling through the column per unit time.

Retention time = The elapsed time between sample injection and detection.

Adjusted Retention Time = The time required by a retained solute to travel through the column beyond the time required by the un -retained solvent.

Linear Flow Rate = The distance traveled by the solvent per unit time.

Retention factor = Describes the amount of time that a sample spends in the stationary phase relative to the mobile phase. It is sometimes also called the capacity factor or capacity ratio.

Relative Volume = Volume of the mobile phase required to elute a solute from the column.

Relative Retention = Ratio of the adjusted retention times or retention factors of two solutes. It is sometimes also called the separation factor.

Partition coefficient = The ratio of the solute concentrations in the mobile and stationary phases.
