Using the standard heats of formation below, what is the heat of reaction when sulfur dioxide reacts with oxygen to form sulfur trioxide? 2so2(g) + o2(g) → 2so3(g) ∆hf° so2(g) = –298.8 kj/mol ∆hf° so3(g) = –395.7 kj/mol –193.8 kj –201.9 kj –492.6 kj –694.5 kj

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.
