Predict how changes effects equilibrium for N2(g) + 3H2(g) -----> 2NH3(g) + heat
a. add heat
b. remove heat
c. add NH3(g)
d. remove NH3(g)
Le Chatelier's Principle says, in ordinary terms, that a system in equilibrium tries to undo what we do to it.
a. This system produces heat. Therefore, if we ADD heat to it it must try to get rid of it. How can it do that? Simple. By shifting to the left it USES heat and that's how it gets rid of what we've added.
With that you should be able to do the others.
Does that mean when heat is added it favors the reactant side?
