[az][b]^4=k
[ab2]^2
as this reaction takes place at higher temperatures, it is observed that the equilibrium shifts toward the products. the
reaction is ?
1) exothermic
2)endothermic

I think D. shift the equilibrium reaction to favor the endothermic process

Explanation:

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

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.
