- Its all about entropy of mixing. Consequently, chemical reactions never go to completion.
- The equilibrium constant K quantifies the extent to which a reaction has gone to completion.
- K and its temperature dependence allow one to determine the change in Gibbs free energy, enthalpy, and entropy, associated with the reaction.
- All thermodynamic functions are defined relative to a standard state (temperature, pressure, and concentration).
When nitrogen triiodide, the dark colored solid, is dry, it is very sensitive to touch or any vibration. Simply touching it with a feather causes it to explode or detonate. One detonation causes another to occur. One product of the reaction is violet iodine vapor.
A mere touch of a feather ... .. causes dry nitrogen triiodide to explode. | . |
