What is the reaction quotient, Q, for this system when [N2] = 2.00 M, [H2] = 2.00 M, and [NH3] = 1.00 M at 472°C?
cupoosta [38]

Answer : The value of reaction quotient, Q is 0.0625.

Solution : Given,

Concentration of N_2 = 2.00 M

Concentration of H_2 = 2.00 M

Concentration of NH_3 = 1.00 M

Reaction quotient : It is defined as a concentration of a chemical species involved in the chemical reaction.

The balanced equilibrium reaction is,

N_2+3H_2\rightleftharpoons 2NH_3

The expression of reaction quotient for this reaction is,

Q=\frac{[Product]^p}{[Reactant]^r}\\Q=\frac{[NH_3]^2}{[N_2]^1[H_2]^3}

Now put all the given values in this expression, we get

Q=\frac{(1.00)^2}{(2.00)^1(2.00)^3}=0.0625

Therefore, the value of reaction quotient, Q is 0.0625.

¿El agua salada es una mezcla homogénea o heterogénea?
Sedbober [7]

The question is in another language, so the English translation of the question is as follows:

Is salt-water a hom.ogeneous or heterogeneous mixture?

Answer:

Hom.ogenous mixture

Explanation:

There are two types of mixtures hom.ogenous and hetergenous.  a heterogeneous mixture has two or more visible phases while a hom.ogeneous mixture is composed of a single visible phase.

The salt-water is hom.ogeneous because the solve dissolve evenly in throughout the entire salt-water sample and gives visible phase.

Hence, the correct option is "hom.ogenous mixture".
