Which one of the following is a correct formation reaction that properly defines a delta Hf value? The answer is 1/2N2(g) + 2O2 = NO2(g) Please explain. I'm having a hard time understand this question. The other answer options is b) N2(g) + 2O2(g) = 2NO2 c) H2(g) + O(g) = H2O d) 3H(g) + N(g) = NH3(g) e) 2NH(g) = 3H2(g) + N2 I also don't understand why it's not the other options.
