describe how to use le chateliers principle to predict the possible ways a chemical system can respond to…

Answer:

Le Chatelier's principle states that when a chemical system at equilibrium is subjected to a change (such as in concentration, temperature, or pressure), the system will shift in a direction that counter - acts the change to re - establish equilibrium. For changes in concentration, if a reactant is added, the equilibrium shifts to the right to consume the added reactant and produce more products. If a product is removed, the equilibrium also shifts to the right to replace the removed product. For changes in temperature, in an exothermic reaction, increasing the temperature shifts the equilibrium to the left (towards the reactants) as the reverse reaction absorbs the added heat. In an endothermic reaction, increasing the temperature shifts the equilibrium to the right (towards the products) as the forward reaction absorbs the heat. For changes in pressure (in reactions involving gases), increasing the pressure shifts the equilibrium towards the side with fewer moles of gas, and decreasing the pressure shifts it towards the side with more moles of gas.

Brief Explanations:

Based on Le Chatelier's principle concepts regarding concentration, temperature, and pressure changes on chemical equilibria.
