most cells are exothermic in the spontaneous direction so applying le chateliers principles to temperature rise would cause a decrease in Ecell because equilibrium would shift backwards
what is the effect of concentration on an ECell.
Applying le chateliers principles. increasing concentration of reactants would increase the Ecell. Decreasing reactants would cause the Ecell to decrease.
Explain why the voltage remains constant in a fuel cell
The reagents are continuously supplied so their concentrations remain constant
