So that is negative zero point 44. Now, I put this negative here in here because we want to convert this to an oxidation because in this anode oxidation that reduction occurs and that's why we have the negative sign here. So what we get is these negatives become a positive and we basically add this guy to this guy and we get zero point 37 volts. This is our cell voltage of our electrochemical cell. Now, in the previous lecture we learned that there's a relationship between our cell voltage and our equilibrium constant, namely this equation here. Now, we also saw in that same lecture that we can convert this formula at 25 degrees Celsius to the following formula.
