How this calculator works
Enter initial equilibrium constant k₁, reaction enthalpy (kj/mol), initial temperature (k), final temperature (k). CalcStack applies the displayed formula and reports each intermediate planning value with the units shown.
Formula / method
ln(K₂/K₁) = −ΔH/R × (1/T₂ − 1/T₁)
Worked example
Use the documented default inputs to model van’t hoff equilibrium shift.
Assumptions and limitations
Inputs represent stable average operating conditions and the displayed equation applies.
This is a planning model; real systems and measurements can require domain-specific corrections.
