In the reversible reaction: 2no2 (g) ⇌ n2o4 (g) the formation of dinitrogen tetroxide releases heat and the formation of nitrogen dioxide absorbs heat. if the reaction is at equilibrium and the temperature increases, what will the effect be? a. nitrogen dioxide absorbs heat and changes from gas to liquid. b. the equilibrium will shift so that there is more nitrogen dioxide. c. the equilibrium will shift so that there is more dinitrogen tetroxide. d. dinitrogen tetroxide absorbs heat and changes from gas to liquid.

B. The equilibrium will shift so that there is more nitrogen dioxide.

Explanation:

Hello,

By considering that the mentioned reaction is exothermic, it means that the heat is like a product, if heat is added (increase the temperature) the equilibrium will shift leftwards, contributing to the inverse reaction; it is the formation of more nitrogen dioxide by recalling the Le Chatelier's principle.

Best regards.

Option (B) is the correct answer.

Explanation:

According to Le Chatelier's principle, any disturbance causes in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.

For example,

When we increase the temperature then the reaction will shift in a direction where there will be decrease in temperature.

This, means that the reaction will shift in the backward direction.

Thus, we can conclude that if the reaction is at equilibrium and the temperature increases, the equilibrium will shift so that there is more nitrogen dioxide.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
