You received different answers because you didn't make it clear which way the reaction is going to obtain delta H of +92.4 kJ and/or some of the responders didn't note that it is delta Ho.
delta Ho is the heat of FORMATION which means
1/2 N2 + 3/2 H2 ==> NH3 delta Ho = delta Hrxn = 46.2 kJ/mol
So for your reaction, we have
N2 + 3H2 ==> 2NH3 for which delta H rxn = +92.4 kJ.
That makes the equation I've written an endothermic reaction and adding heat will shift it to the right (to the NH3 side)
Consider the following reaction at equilibrium:
2NH3 (g)<-> N2 (g) + 3H2 (g) ΔH° = +92.4 kJ
