Louis Le Chatelier

Henri Louis Le Chatelier was born in Paris, France on October 8th, 1850 and died on September 17th, 1936 in Miribel-les-Echelles, France. Le Chatelier was a chemist who had discovered the” Le Chatelier’s Principle” that proved if any modification or stress is enforced on a chemical system at equilibrium, the system will in turn regulate and adjust to a new equilibrium neutralizing the preceding change. Possible changes or stresses that may transpire may include temperature, concentration, pressure, volume, catalysts and noble gases.

Henri Le Chatelier had grown up in a family background with a vast amount of knowledge about science and technology as his family included architects, scientists and engineers as well. He had come from a Roman Catholic Family, and he had five siblings (1 sister and four brothers). Henri’s mother had raised him and his siblings in a very strict fashion, where discipline and respect were to be implemented. His father, Louis Le Chatelier and relatives were a major influential role model for Henri, as they contributed towards the origin of the Martin-Siemens steel and iron industry, railway production, mining, and the French aluminum industry. This had a key impact on the way Henri’s career advanced.

During the Franco-Prussian War (1870-1871), Le Chatelier had been a lieutenant for the army. He had left the army and returned to college where he attended College Rollin in Paris. While being there, he had received an undergraduate degree in the year’s of1887 and 1868. One year later, on October 25th, 1869 he had decided to follow the same path as his father previously had, and enrolled at Ecole Polytechnique where he had attained excellent results. The next year, during September of 1870, Le Chatelier...

6. Noble Gases

Example: H2(g) + I2(g) + He(g) = 2HI(g) + He(g)

 Due to the fact that noble gases tend to rarely react with other elements most of the time, then adding one to a reaction will have no effect, or impose no shift in equilibrium when the volume remains the same.

Equilibrium will shift to the side of the reaction with fewer molecules when volume is increased.

3. a) Equilibrium will shift right as oxygen is increased

b) Equilibrium will shift in the opposite direction/away from the energy when you increase the temperature

c) Equilibrium will shift in the right direction when NO(g) if removed/taken away from the system

d) Equilibrium will remain neutral with no net change when argon gas (noble gas) is added to the system and when the volume remains the same as well.
