All of those are right. For the endothermic rxn (or exothermic) look at it this way and it will make a lot of sense.
A + B ==> C + heat for exothermic so adding heat works just like adding a reagent; i.e., adding A or B shifts to the right. Adding C shifts to the left. Adding heat shifts to the left.
Endothermic rxn.
A + B + heat ==> C
Adding A or B or heat shifts to the right. Adding C shifts to the left.
Ok, so using Le Chatelier's Principle
If you add heat to an exothermic reaction, the equilibrium will shift to the left.
If you remove heat to an exothermic reaction, the equilibrium will shift to the right.
What is it for an ENDOTHERMIC reaction?
If you add a substance, the equilibrium will shift to the other side.
If you remove a substance, the equilibrium will shift to the same side.
If you increase pressure/decrease volume, then the equilibrium will shift to the side with the less moles.
If you increase volume/decrease pressure, then the equilibrium will shift to the side with more moles.
Please tell me if this is right, thank you :)
