Le Chatelier–Braun principle analyzes the qualitative behaviour of a thermodynamic system when a particular one of its externally controlled state variables, say , changes by an amount , the 'driving change', causing a change , the 'response of prime interest', in its conjugate state variable , all other externally controlled state variables remaining constant.
This can be seen as a consequence of Le Chatelier's principle because the inhibitor binds to both the enzyme and the enzyme-substrate complex equally so that the equilibrium is maintained. However, since some enzyme is always inhibited from converting the substrate to product, the effective enzyme concentration is lowered.

Barium iodate, Ba(IO 3) 2, has a solubility product K sp = [Ba 2+][IO 3 −] 2 = 1.57 x 10 −9.Its solubility in pure water is 7.32 x 10 −4 M. However in a solution that is 0.0200 M in barium nitrate, Ba(NO 3) 2, the increase in the common ion barium leads to a decrease in iodate ion concentration.
(a) Le Chatelier's principle also states that when there is an external constraint on a system, a behavioural shift in the system occurs so as to annul the effect of that change. (b) Where a shock initially induces positive feedback (such as thermal runaway), the new equilibrium can be far from the old one, and can take a long time to reach.
The Portevin-Le Chatelier effect occurs in the specific case where solute drag creep is occurring and there is an applied stress, with a material dependent range, on the sample. The applied stress causes the velocity of the dislocations to increase, allowing the dislocation to move away from the solute.
Le Chatelier was born on 8 October 1850 in Paris and was the son of French materials engineer Louis Le Chatelier and Louise Durand. His father was an influential figure who played important roles in the birth of the French aluminium industry, the introduction of the Martin-Siemens processes into the iron and steel industries, and the rise of railway transportation.
By Le Chatelier's principle, the release of CO 2 from the lungs pushes the reaction above to the left, causing carbonic anhydrase to form CO 2 until all excess protons are removed. Bicarbonate concentration is also further regulated by renal compensation , the process by which the kidneys regulate the concentration of bicarbonate ions by ...
