Currently I am learning Equilirium, and when I get to the Dymanic Equilirium or rather the LeChatelier's Principle, I became confused. Well, not exactly confused, but don't fully understand the concept. I understand that whenever a system at equilibrium is subjected to a stress, then the equilibrium will shift in a direction so as to relieve that stress. And the stresses may be a change in temperature, concentration and/or pressure(volume).

 

When either one of those stresses occurred I am having a difficulty to decide which direction the equilibrium will move. Right or Left? (Or even no change).

 

Use this example: 2NO(g) + O2(g) <===> 2NO2(g) + energy

 

(a) What happens if the temperature decreased?

(b) the concentration of NO(g) is descreased?

© the concentration of NO2(g) is increased?

(d) the volume of the system is decreased?

 

Any helpful hints or concepts would be accepriated.

this website explains it well. Read there and see if it helps you at all

 

Cheers,

Yesterday I had a Chemistry test and there were several questions on LeChatelier's Principle, and I got all of the answers correct! *pats on my back* but overall, I didn't do too well on the test.
