Most ethylene (C₂H₄), the starting material for producing polyethylene, comes from petroleum processing. It also occurs naturally as a fruit-ripening hormone and as a component of natural gas.
(a) The heat transferred during combustion of C₂H₄ is -1411 kJ/mol. Write a balanced thermochemical equation.

Answer :

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O + 1411 kJ/mol is a balanced thermochemical equation.

What is Exothermic Reaction ?

A reaction where energy is released in form of heat or light is called Exothermic reaction.

Reactants → Product + Energy

What is Balanced Chemical Equation ?

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now write the balanced chemical equation

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O     ΔH = -1411 kJ/mol

Here sign of change is enthalpy is negative so the reaction is exothermic that means heat is a product.

The balanced thermochemical equation is

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O + 1411 kJ/mol

Thus from the above conclusion we can say that C₂H₄ + 3O₂ → 2CO₂ + 2H₂O + 1411 kJ/mol is a balanced thermochemical equation.
