Chemical activityEquilibrium constant

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Thermodynamic equilibrium constants are products of activities raised to stoichiometric powers under a stated reaction convention.

How to interpret this relation type

The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Chemical equilibriumEquilibrium constant

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

At fixed temperature, the equilibrium activity quotient for a specified reaction equals its equilibrium constant.

How to interpret this relation type

The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Standard reaction Gibbs energyEquilibrium constant

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

For a reaction and standard-state convention at temperature TT, equilibrium thermodynamics gives ΔrG=RTlnK\Delta_\mathrm rG^\circ=-RT\ln K when the activity-based equilibrium constant is defined consistently.

How to interpret this relation type

Record a genuine theorem implication that is not part of the target definition; these edges may point toward a weaker structure.

Chemical standard stateEquilibrium constant

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

A thermodynamic equilibrium constant uses activities relative to specified standard states and is dimensionless under the adopted convention.

How to interpret this relation type

The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
