Finding K: Solid State Excluded?

[higherme]

when finding K, do we include the liquid state? I know the solid state is not included

It would help if you provide an example with your question.

If I'm interpreting it correctly, then the answer is yes. Strictly speaking, we need to account for activities of liquids in the reaction, but in certain cases, the activities are close to 1 (most any aqueous reaction) and may be ignored. When dealing with near ideal liquid-liquid solutions or with mixtures of immiscible liquids, the actual molar concentration of the liquid may be used in the place of its activity (the same substitution that is made for most solutes in dilute solutions).

because it is not a fluid

Thank you for your question. In scientific terminology, the letter "K" can have different meanings depending on the context. Without further information, it is difficult to provide a specific response to your inquiry. However, assuming that "K" refers to a physical property or state, such as temperature or phase, here is a general explanation:

In general, when discussing the physical properties or states of matter, scientists typically refer to the three main states: solid, liquid, and gas. These states are determined by the arrangement of particles and the strength of their interactions. Solids have tightly packed particles with strong interactions, liquids have less tightly packed particles with weaker interactions, and gases have particles that are far apart with very weak interactions.

In this context, it is important to note that the state of matter is determined by the temperature and pressure of the system. At a specific temperature and pressure, a substance will exist in a specific state (e.g. solid, liquid, or gas). For example, at room temperature and atmospheric pressure, water exists as a liquid. If the temperature is lowered, it will turn into a solid (ice) and if it is raised, it will turn into a gas (water vapor).

Therefore, when finding "K", it is important to consider the temperature and pressure at which the substance is being studied. If the substance is being studied at a temperature and pressure where it exists as a liquid, then the liquid state should be included in the analysis. However, if the substance is being studied at a temperature and pressure where it exists as a solid, then the solid state should be included and the liquid state should not be considered.

In summary, when discussing the physical properties or states of matter, it is important to clarify the temperature and pressure at which the substance is being studied in order to determine which states should be included in the analysis.
