Dinitrogen tetraoxide and nitrogen dioxide are two gases that exist in equilibrium at a range of temperatures. no2 is a reddish brown gas while n2o4 is colorless. at high temperature the red color is strong. at low temperature the gas has less color. if we represent the equilibrium as: 2 no2(g) n2o4(g)

if we represent the equilibrium as: 2 no2(g) doublearrow. gifn2o4(g)
we can conclude that:

this reaction is:

a. exothermic
b. endothermic
c. neutral
d. more information is needed to answer this question.

A. Exothermic

Explanation:

Let's consider the following reaction at equilibrium.

    2 NO₂(g)       ⇄      N₂O₄(g)

reddish brown         colorless

In order to assess the effect of temperature on the equilibrium, we need to consider Le chatelier's principle: If a system at equilibrium suffers a perturbation, it will shift its equilibrium position to counteract such perturbation.

Let's suppose the reaction is exothermic.

Since it coincides with the experimental results, we can conclude that the reaction is exothermic.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
