Question

Which of the following is the most likely cause for the increase in pressure observed in the container as the reaction reaches equilibrium?
a) a decrease in the strength of intermolecular attractions among molecules in the flask
b) an increase in the strength of intermolecular attractions among molecules in the flask
c) an increase in the number of molecules, which increase the frequency of collisions with the walls of the container
d) an increase in the speed of the molecules than then collide with the walls of the container with greater force

Answer 1

Answer:

c) an increase in the number of molecules, which increase the frequency of collisions with the walls of the container.

Explanation:

Hello!

When in a chemical reaction the amount of mole of products is greater than the amount of mole of reagents, an increase in pressure is observed upon reaching equilibrium.

Increases in temperature can also produce an increase in pressure although in some cases an increase in temperature may occur under isobar conditions (constant pressure).
