Le Chateiier’s principle

For this exothermic reaction, the value of K decreases as the temperature increases, as predicted by Le Chateiier s principle. 

The Response of an Equilibrium System to a Stress Is Given by Le Chateiier s Principle... 

This experiment demonstrates that all reactants and products are present in the reacting system at equilibrium. Additionally, increasing the concentrations of the products (Fe or SCN ) shifts the equilibrium to the left, whereas decreasing the concentration of the product Fe shifts the equilibrium to the right. These results are just as predicted by Le Chateiier s principle. 

Le Chateiier s principle simply summarizes the observed behavior of equilibrium systems therefore, it is incorrect to say that a given equilibrium shift occurs because of Le Chateiier s principle. 

The value of is different for this equation, but the changes described in the problem have the same effects. Thus, shifts in equilibrium position predicted by Le Chateiier s principle are not affected by a change in the balancing coefficients.
