When in any system at equilibrium state,pressure,temperature,and concentration are changed,then the equilibrium shifts in such a direction as to neutralize the effect of the change. This is known as:
- AFirst law of thermodynamics
- BLe Chatelier's principle
- COstwald's rule
- DHess's law of constant heat summation
