Asked by Shaun
Consider the reaction N2+O2-->2NO with Delta H=43.2kcal.
When 50.0g of N2 react with an excess of oxygen, how much heat is generated/consumed?
I know that this is an endothermic reaction b/c of the + delta H, is there some sort of formula to use here? I have no idea where to start...can someone walk me through this? I'm lost!!!

Yes, it's endothermic and you're right for the reason, too.
The equation tells you that 43.2 kcal is consumed by 1 mol N2 (28g). All you need to do is proportion that out for 50 g.
43.2 kcal x (50/28) = ?
