When nitrogen and hydrogen gas combine to make ammonia, the chemical equation looks like this:

2N2 + 3H2 => 2NH3

If the hydration energy of 2N2 + 3H2 is equal to + 2251.3 kJ/mol and the lattice energy of 2NH3 is equal to -2343.52 kJ/mol, what is the total energy change of this reaction and is the reaction endothermic or exothermic?
