Using this reversible reaction, answer the following:
n2o4 < --> 2no2
(colorless) (reddish-brown)

-as the temperature increased, what happened to the [n2o4]?

-was the formation of reactants or products favored by the addition of heat?

-which reaction is exothermic?

-if the change of enthalpy of this reaction when proceeding left to right is 14 kcal, which chemical equation is correct?

n2o4 < --> 2no2 + 14 kcal
n2o4 < --> 2no2, hr = +14 kcal
n2o4 + 14 kcal < --> 2no2
n2o4 < --> 2no2, hr = -14 kcal

Using this reversible reaction, answer the following: n2o4 < --> 2no2 (colorles

Question 1.

The concentration of [N2O4] will decrease.

Explanation:As the reverse reaction which is the formation of N2O4 is an exothermic reaction and the formation of NO2 is an endothermic reaction.Hence heating will favor the forward reaction and stops the reverse reaction.N2O4 --> 2NO2So the concentration of N2O4 decreases.Question: 2.

The formation of the products is favored by the addition of heat.

Explanation:As the reverse reaction which is the formation of N2O4 is an exothermic reaction and the formation of NO2 is an endothermic reaction.So the addition of heat will favor endothermic reaction.Hence the formation of NO2 will be favored which is a product.Question no.4:

The reverse reaction is an exothermic reaction.

N2O4 <-- 2NO2.

Explanation:N2O4 which is a reactant in this reaction is colorless compound.Its breakdown absorbs energy and its formation release energy in form of heat.So the reverse reaction which releases energy is an exothermic reaction.Question no. 4

The correct option is D which is N2O4 <--> 2NO2, HR = -14 kcal.

Explanation:Enthalpy is the change in energy in reactants and products.It is actually the difference in energies of products and reactant.As the enthalpy change from left to right, it means reactants have internal energy 14 kcal high than products and it will be released.And in option D which is shown as HR = -14 kcal.

no statements shown

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl

answered: Guest

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.
