Le Chatelier's principle (stress and shift) (If stress applied, equilibrium shifts to partially oppose the stress)

jee-mainjee-advancedneet-ug

If stress applied, equilibrium shifts to partially oppose the stress

What each symbol means

SymbolWhat it stands for
shiftNet reaction direction restoring partial relief of stress
stressChange in concentration, partial pressure, volume, or temperature

When to use this

Valid qualitative predictor; K changes only with T, not with concentration or pressure (for ideal systems).
