Sry :p decided to use cyan to represent exothermic because it gives out heat so itself cool haha. Thanks in advance :D

NotAbod:
Forward reaction: Exothermic
Reverse reaction: Endothermic

Now, Increasing temperature --> reaction shifts to endothermic side (In temp -> En)
why? Reaction will try to reach equilibrium again so it will shift to the side which absorbs heat, i.e. endothermic side.

Decreasing temperature --> reaction shifts to exothermic side
why? same reason, reaction will try to reach equilibrium again so it will shift to the side which gives out heat, i.e. exothermic side.

NotAbod:
And Le Chatelier's Principle could help you understand better.
when there's a change in the system at equilibrium, the system will adjust to re-establish enquilibrium by counteracting (oppose) the imposed change

My teacher actually explained equilibrium to us in a funny way. If you are watching Tv and your younger brother comes and changes the channel, what would you do? counteract. how? by changing the channel back to what you were watching.
This is the same case, you increase temperature or pressure and the reaction will counteract. It will try to do the opposite of what you have done.

skylite:
Ahhh i get it now! :D Thanks a lot NotAbod~!!
My confidence increased a bit  ;D

Chem paper4 tomorrow .. Good luck for everyone whose doing the same thing

NotAbod:
No problem.
Good luck.
