Question

Le Chatelier's principle is very powerful. It states that any system initially at equilibrium, when subjected to a change in temperature or pressure, will react in such a way as to reduce stress. Discuss this principle for equilibrium in relation to the expected shifts in voltage for changes in reactant and product concentrations seen from the pressure- dependent component of the Nernst equation. Can you tell ''just by looking'' if the voltage will go up or down for a given shift in concentration of reactants or products?

Explanation / Answer

Nernst equation. The equation allows us to calculate the cell potential of any galvanic cell for any concentrations.

At any specific temperature, the Nernst equation derived above can be reduced into a simple form. For example, at the standard condition of 298 K (25
