Jinsi ya kukokotoa Thermochem
Thermochem ni nini?
Thermochemistry measures heat involved in reactions: ΔH (enthalpy change), ΔS (entropy change), ΔG (Gibbs free energy).
Mwongozo wa Hatua kwa Hatua
- 1Input reaction and temperature
- 2Calculate ΔH from bond energies or Hess's law
- 3Determine spontaneity: ΔG = ΔH - TΔS
Mifano Iliyotatuliwa
Ingizo
Combustion: exothermic (ΔH < 0), entropy increases (ΔS > 0)
Matokeo
Spontaneous at all temperatures (ΔG < 0)
Makosa ya Kawaida ya Kuepuka
- ✕Assuming exothermic always spontaneous
- ✕Not accounting for temperature dependence
Maswali yanayoulizwa mara kwa mara
When is reaction spontaneous?
ΔG < 0; depends on temperature through ΔH - TΔS balance.
