van Hove isotherm equation

physical quantity that determines direction

The physical quantity that determines the limit

The standard molar Gibbs free energy change value of a chemical reaction is only a function of temperature.

When a chemical reaction reaches equilibrium

For example, the decomposition of Ag2O

low pressure gas phase reaction

The total pressure is constant, which has the same effect as decompression

Changes in total pressure have no effect

When A and B are added in proportion to the coefficients of the reaction equation, the equilibrium content of the product will be the largest.

Calculate the standard equilibrium constant of thermodynamics

Approximately estimate the likelihood of a reaction

liquid mixture reaction system

solution reaction system

Reactions involving gas phase and condensed phase (liquid phase, solid) are called complex-phase chemical reactions

The thermodynamic equilibrium constant and empirical equilibrium constant of a multi-phase chemical reaction are only related to the pressure of the gaseous substance and have nothing to do with the condensed phase.
