Which type of reaction is the Haber process: N2(g) + 3 H2(g) → 2 NH3(g) + heat? * exothermic, with an increase in entropy
exothermic, with a decrease in entropy
endothermic, with an increase in entropy
endothermic, with a decrease in entropy

exothermic, with a decrease in entropy

Explanation:

Whenever you produce heat as a product in a reaction, the reaction is exothermic. To determine entropy, we know we have 4 moles of gas on reactant (1 from N2 and 3 from H2) and in produce side we only have two moles (2 from NH3) thus since we are decreasing the number of gas molecules, there is going to be less disorder, hence decrease in entropy.
