Electrochemistry questions

At equilibrium, E$\text{}_{cell}$start text, end text, start subscript, c, e, l, l, end subscript calculates to a value of 0 and the battery is considered dead because Q becomes K$\text{}_{eq}$start text, end text, start subscript, e, q, end subscript and K$\text{}_{eq}$start text, end text, start subscript, e, q, end subscript has a value of 0.

Increasing the concentration of the reactants will increase the value of E$\text{}_{cell}$start text, end text, start subscript, c, e, l, l, end subscript.

This equation is used to figure out the standard cell potential at any concentration, partial pressure, or temperature.

At standard conditions, Ecell = E°cell because all the concentrations are 1 M at an ambient temperature of 273 K.
