So far we have only spoken about electrochemical cells in which the reactants and products are both at standard state conditions. This means when I showed you the relationship between the concentration of reactants and products and the electrochemical cells cell voltage I did this on the standard state conditions. However, most reactions actions do not occur under standard state conditions. This means we must revisit the topic of the relationship between the concentrations and the cell voltage and adjusted for nonstandard state conditions. So, to begin, let's first talk about standard state conditions. So, standard state conditions simply means a concentration of one molar and a pressure of 1 bar and the temperature could be anything.
