Thermochem ಅನ್ನು ಹೇಗೆ ಲೆಕ್ಕ ಹಾಕುವುದು
Thermochem ಎಂದರೇನು?
Thermochemistry measures heat involved in reactions: ΔH (enthalpy change), ΔS (entropy change), ΔG (Gibbs free energy).
ಹಂತ-ಹಂತದ ಮಾರ್ಗದರ್ಶಿ
- 1Input reaction and temperature
- 2Calculate ΔH from bond energies or Hess's law
- 3Determine spontaneity: ΔG = ΔH - TΔS
Worked Examples
ಇನ್ಪುಟ್
Combustion: exothermic (ΔH < 0), entropy increases (ΔS > 0)
ಫಲಿತಾಂಶ
Spontaneous at all temperatures (ΔG < 0)
Common Mistakes to Avoid
- ✕Assuming exothermic always spontaneous
- ✕Not accounting for temperature dependence
Frequently Asked Questions
When is reaction spontaneous?
ΔG < 0; depends on temperature through ΔH - TΔS balance.
