The principle that states that if a stress is applied to a system at equilibrium, the system nullifies the effect of stress as far as possible is:

Correct answer: B. Le-Chatelier

  • A. Haber's
  • B. Le-Chatelier
  • C. Boyle's
  • D. Charles'

Explanation

The principle is Le Chatelier's Principle. It states that if a stress is applied to a system at equilibrium, the system will adjust to counteract the effect of the stress, shifting the equilibrium to minimize the disturbance.

About Chemical Equilibrium

Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
