Sagot :
The addition of the product of volume and pressure along with internal energy is called enthalpy. The change in the enthalpy at 1 atm is 24.3 kJ. Thus, option d is correct.
What is enthalpy?
Enthalpy is the measurement of the heat or the energy present in a system that has a constant pressure in the thermodynamic system.
The balanced equation is shown as,
Sn (s) + SnO₂ (s) → 2SnO (s) , ΔH° = 16.2 kJ
The enthalpy change for the reaction is for 2 moles of Tin(II) oxide. So, for 3 moles of Tin(II) oxide produced in the reaction the enthalpy change will be given as,
= (16.2 kJ × 3 mol) ÷ 2 mol
= 24.3 kJ
Therefore, option d. 24.3 kJ is the enthalpy change.
