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. Normally the temperature is 25 degrees Celsius or 298 degrees Kelvin. But it could really be anything. So, in a previous lecture we saw that the relationship between equilibrium constant K on the standard conditions is the following log of base ten of k is equal to number of moles of electrons and times our cell voltage on the same state conditions divided by 0.0592.
