Given the equation representing a system at equilibrium:
n2(g) + 3h2(g)< ==> 2nh3(g) + energywhich changes occur when the temperature of this system is decreased?
(1) the concentration of h2(g) increases and the concentration of n2(g) increases.
(2) the concentration of h2(g) decreases and the concentration of n2(g) increases.
(3) the concentration of h2(g) decreases and the concentration of nh3(g) decreases.
(4) the concentration of h2(g) decreases and the concentration of nh3(g) increases.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
