bottled soda?Another everyday example of dynamic equilibrium is the carbon dioxide present in bottles of soda. In a bottle of soda, carbon dioxide is present with the bottle in two separate states, gaseous and aqueous states of carbon dioxide are both present. These two forms of carbon dioxide in the bottle are in fact at dynamic equilibrium. The bottle is air tight, creating a closed system, and the gaseous carbon dioxide is dissolving into the soda at the same rate the that is aqueous carbon dioxide is being converted back into its gaseous form. This reaction is represented by them following equation:
CO2(g) → CO2(aq) |
