N2 + O2 -> 2NO enthalpy change = +180.6kJ

Question

c) what is the enthalpy change for the formation of one mole of nitrogen monoxide?

Okay, I know this question is super easy, but I don't know how to do it; if someone could please give me a detailed explaination on how to do a full solution, I would be extremely grateful.

Answer 1

If this is 180.6 kJ for the reaction, that makes it for 2 mol NO. You want 1 mol NO; therefore, take 1/2 of 180.6.
