How do these things shift the direction of a chemical reaction?:

-adding/removing reactants
-adding/removing products
-adding/removing energy

Thanks!

It depends upon the equation and whether the reaction is exothermic or endothermic. Post the entire problem and tell us what you think the answer is. If you don't know where to start, tell us what it is about the problem that you don't understand. That way we can help.

That is all it says. But I think I actually figured it out. Thanks though.
