The lead-acid storage battery is the oldest rechargeable battery in existence. It was invented in 1859 by French physician Gaston Plante and still retains application today, more than 150 years later. There are two reactions that take place during discharge of the lead-acid storage battery. In one step, sulfuric acid decomposes to form sulfur trioxide and water: H₂SO4(1)→ SO3(g) + H₂O(1) In another step, lead, lead(IV) oxide, and sulfur trioxide react to form lead(II) sulfate: Pb(s) + PbO₂(s) + 2 SO3(g) → 2 PbSO4(s) Calculate the net change in enthalpy for the formation of one mole of lead (II) sulfate from lead, lead(IV) oxide, and sulfuric acid from these reactions.

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
Question
Transcribed Image Text:The lead-acid storage battery is the oldest rechargeable battery in existence. It was invented in 1859 by French physician
Gaston Plante and still retains application today, more than 150 years later.
There are two reactions that take place during discharge of the lead-acid storage battery. In one step, sulfuric acid
decomposes to form sulfur trioxide and water:
H₂SO4(1) SO3(g) + H₂O(1)
In another step, lead, lead(IV) oxide, and sulfur trioxide react to form lead(II) sulfate:
Pb(s) + PbO₂(s) + 2 SO3(g) → 2 PbSO4(s)
☐ kJ
ΔΗ=+113. kJ
Calculate the net change in enthalpy for the formation of one mole of lead(II) sulfate from lead, lead(IV) oxide, and sulfuric
acid from these reactions.
Round your answer to the nearest kJ.
