When in any system at equilibrium state pressure, temperature and concentration is changed then the equilibria shifted to such a direction which neutralize the effect of change. This is known as [MP PMT/PET 1988; DPMT 1985] (a) First law of thermodynamics (b) Le-chatelier's principle (c) Ostwald's rule (d) Hess's law of constant heat summation
Correct option is B) when in any system at equilibrium state pressure , temperature and concentration is changed then the equilibrium shifted to such a direction which neutralize the effect of change . this is known Le-Chatelier's principle Hence B is correct answer
