tell me if im right or wrong
For Kc,it only includes gas and aq
for Kp, only includes gas. What about vapor pressure, do i use (g) notation to represent it
You are partially right. The equilibrium constant, Kc, represents the concentrations of species in a chemical equilibrium, and it includes all species, whether they are in the gas, liquid, or aqueous (dissolved) phases. However, the equilibrium constant, Kp, specifically represents the partial pressures of species in a gaseous equilibrium.
Vapor pressure refers to the pressure exerted by a vapor in equilibrium with its liquid or solid phase. In the context of equilibrium constants, if you want to include the vapor pressure of a species, you would use the "(g)" notation to represent it, indicating that the substance is in the gaseous phase.
So, in summary:
- Kc includes all species, regardless of phase (gas, liquid, or aqueous).
- Kp specifically includes species in the gas phase.
- To represent vapor pressure, you use the "(g)" notation.
