- Equilibrium in Chemistry
- Chemical equilibrium.
- DYNAMIC
- Rate of forward and reverse reactions are equal.
- Concentration of products and reactants are CONSTANT but not always the same
- CLOSED SYSTEM
- DYNAMIC
- Equilibrium constant
- Changes
- Concentration
- Temperature
- Pressure
- Kc = [C]c[D]d / [A]a [B]b
- Kc > 1 means that there are more products than reactants. Equilibrium lies to the RHS
- Kc >> 1 (greater than 10^10) reaction has gone to completion
- Kc < 1 means that there are more reactants than products. Equilibrium lies to the LHS
- Kc Ksp, the solid will precipitate out of solution
- Kc > 1 means that there are more products than reactants. Equilibrium lies to the RHS
- Changes
- Le Chatelier's Principle
- Solubility equilibria
- Gas-liquid chromatograp-hy
- Principles the same as TLC
- Mobile phase
- Unreactive gas
- Stationary phase
- Small amount of liquid with a high boiling point.
- Kpc
- The partition coefficient: The distribution of the components of the sample between the stationary and mobile phases.
- [Component in stationary phase] / [component in mobile phase]
- Chemical equilibrium.
