Chemical Thermodynamics ?
Chemical Thermodynamics is a branch of chemistry that deals with the relationship between heat, work, and chemical reactions or with the physical changes of state within the boundaries of thermodynamic systems. It combines principles of thermodynamics with chemical phenomena to explain and predict the direction, extent, and energy changes associated with chemical reactions.
Key Concepts in Chemical Thermodynamics:
- First Law of Thermodynamics (Conservation of Energy)
- Energy cannot be created or destroyed; it can only be transformed from one form to another.
- ΔU=q+w\Delta U = q + wΔU=q+w, where:
- ΔU\Delta UΔU: Change in internal energy of the system.
- qqq: Heat added to the system.
- www: Work done on or by the system.
- Second Law of Thermodynamics
- Entropy (SSS) of an isolated system always increases in a spontaneous process.
- Systems tend to move toward greater disorder or randomness.
- Third Law of Thermodynamics
- The entropy of a perfect crystal at absolute zero (0 K0 \, \text{K}0K) is zero.
- Gibbs Free Energy (GGG)
- Determines the spontaneity of a reaction:
- ΔG=ΔH−TΔS\Delta G = \Delta H – T \Delta SΔG=ΔH−TΔS, where:
- ΔG\Delta GΔG: Change in Gibbs free energy.
- ΔH\Delta HΔH: Change in enthalpy.
- ΔS\Delta SΔS: Change in entropy.
- TTT: Temperature in Kelvin.
- ΔG=ΔH−TΔS\Delta G = \Delta H – T \Delta SΔG=ΔH−TΔS, where:
- ΔG<0\Delta G < 0ΔG<0: Reaction is spontaneous.
- ΔG>0\Delta G > 0ΔG>0: Reaction is non-spontaneous.
- ΔG=0\Delta G = 0ΔG=0: Reaction is at equilibrium.
- Determines the spontaneity of a reaction:
- Enthalpy (HHH)
- Heat content of a system.
- Exothermic reactions (ΔH<0\Delta H < 0ΔH<0) release heat.
- Endothermic reactions (ΔH>0\Delta H > 0ΔH>0) absorb heat.
- Entropy (SSS)
- Measure of the disorder or randomness of a system.
- Greater entropy indicates higher disorder.
- Equilibrium
- At equilibrium, the forward and reverse reaction rates are equal.
- The Gibbs free energy is at its minimum.
- Reaction Quotient (QQQ) and Equilibrium Constant (KKK)
- QQQ: Ratio of product and reactant concentrations at any point during a reaction.
- KKK: Ratio at equilibrium.
- If Q<KQ < KQ<K: Reaction proceeds forward.
- If Q>KQ > KQ>K: Reaction proceeds in reverse.
Applications:
- Predicting the feasibility and direction of chemical reactions.
- Understanding energy changes in biochemical processes.
- Designing efficient energy systems, such as fuel cells.
- Studying phase transitions (e.g., solid to liquid, liquid to gas).
