Answer :

The relationship between the rate at which the nitrous oxide is used :

\text{Rate of disappearance of }N_2O=-\frac{1}{2}\frac{d[N_2O]}{dt}

The relationship between the rate at which the oxygen is used :

\text{Rate of disappearance of }O_2=-\frac{1}{3}\frac{d[O_2]}{dt}

The relationship between the rate at which the nitrogen dioxide is used :

\text{Rate of formation of }NO_2=+\frac{1}{4}\frac{d[NO_2]}{dt}

Explanation :

The general rate of reaction is,

aA+bB\rightarrow cC+dD

Rate of reaction : It is defined as the change in the concentration of any one of the reactants or products per unit time.

The expression for rate of reaction will be :

\text{Rate of disappearance of A}=-\frac{1}{a}\frac{d[A]}{dt}

\text{Rate of disappearance of B}=-\frac{1}{b}\frac{d[B]}{dt}

\text{Rate of formation of C}=+\frac{1}{c}\frac{d[C]}{dt}

\text{Rate of formation of D}=+\frac{1}{d}\frac{d[D]}{dt}

Rate=-\frac{1}{a}\frac{d[A]}{dt}=-\frac{1}{b}\frac{d[B]}{dt}=+\frac{1}{c}\frac{d[C]}{dt}=+\frac{1}{d}\frac{d[D]}{dt}

From this we conclude that,

In the rate of reaction, A and B are the reactants and C and D are the products.

a, b, c and d are the stoichiometric coefficient of A, B, C and D respectively.

The negative sign along with the reactant terms is used simply to show that the concentration of the reactant is decreasing and positive sign along with the product terms is used simply to show that the concentration of the product is increasing.

Now we have to determine the expression for rate of reaction.

The balanced chemical equations is:

2N_2O(g)+3O_2(g)\rightarrow 4NO_2(g)

The relationship between the rate at which the nitrous oxide is used :

\text{Rate of disappearance of }N_2O=-\frac{1}{2}\frac{d[N_2O]}{dt}

The relationship between the rate at which the oxygen is used :

\text{Rate of disappearance of }O_2=-\frac{1}{3}\frac{d[O_2]}{dt}

The relationship between the rate at which the nitrogen dioxide is used:

\text{Rate of formation of }NO_2=+\frac{1}{4}\frac{d[NO_2]}{dt}

Why are most solid ionic compounds electrically nonconductive, whereas aqueous solutions of ionic compounds are good conductors
Allisa [31]

Answer:

there must be free-moving electrons in a compound to conduct electricity.

in solid ionic compounds, there are no free electrons so it can't conduct electricity.

But in aqueous form the forces of attraction are broken and the ions (cations and anions) are free to move. This means there are free electrons that allow the aqueous compound to conduct electricity.

A 2.2 M solution is made by with 0.45 moles of a solute. What is the final volume of this solution?
Savatey [412]

Answer: The final volume of this solution is 0.204 L.

Explanation:

Given: Molarity of solution = 2.2 M

Moles of solute = 0.45 mol

Molarity is the number of moles of solute present divided by volume in liters.

Molarity = \frac{no. of moles}{Volume (in L)}

Substitute the values into above formula as follows.

Molarity = \frac{no. of moles}{Volume (in L)}\\2.2 M = \frac{0.45}{Volume}\\Volume = 0.204 L

Thus, we can conclude that the final volume of this solution is 0.204 L.
