I have re-written the equation as
NH3(g) + O2(g)--> NO(g) + heat
Le Chatelier's Principle says that a system will try to undo what we do to it. Therefore, if we add heat, for example, the system will try to get rid of the extra heat. How can it do that? By shifting to the left (reacting in the reverse direction) because that way some of the added heat will be used up.
The others are done the same way. Someone will be happy to check your answers.
