I have a wonderful line explaining the Le-Chateliers principle--------
"The system always tries to oppose any change in its state"
Example---
1-If temprature inc. then it will try to decrease it and go in the endothermic direction.
2-If we add product in the reaction mixture it tries to reduce it and reaction goes in the forward direction.
3-If we remove the products then it tries to make the conc of products same again and it goes in forard direction.
JUST REMEMBER THE ABOVE LINE AND YOU WILL NOT NEED TO LEARN IT ANY MORE.
Being a genius is 1% luck and 99% perspiration........
