3c2h2(g) → c6h6(g) what is the standard enthalphy change δho, for the reaction represented above? (δhof of c2h2(g) is 230 kj mol-1; (δhof of c6h6(g) is 83 kj mol-1; )

The standard enthalpy change  is -607kJ

Explanation:

The given balanced chemical reaction is,

First we have to calculate the enthalpy of reaction .

where,

We are given:

Putting values in above equation, we get:

The standard enthalpy change  is -607kJ

that tool would be a compass

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.
