Le Chatelier's principle (pronounced ), also called Chatelier's principle or "The Equilibrium Law", can be used to predict the effect of a change in conditions on a chemical equilibrium, the principle is named after Henry Louis Le Chatelier and sometimes Karl Ferdinand Braun who discovered it how?
Karl Ferdinand Braun Karl Ferdinand Braun (6 June 1850 – 20 April 1918) was a German inventor, physicist and Nobel laureate in physics. Braun contributed significantly to the development of radio and television technology: he shared with Guglielmo Marconi the 1909 Nobel Prize in Physics.
Reaction quotient In chemistry, a reaction quotient ("Q") is a function of the activities or concentrations of the chemical species involved in a chemical reaction. In the special case that the reaction is at equilibrium the reaction quotient is constant and equal to the equilibrium constant that appears in the expression of the law of mass action.
