So let's set these guys equal. So we get negative MF times E equals negative RT, notch and log of K.
So we can basically rearrange this guy and solve for our cell voltage. And what we get is the negatives cancel and we bring the M and the F to this side. And we get our cell voltage equal to gas constant times temperature tail and divided by moles of electrons times paradise constant times natural log of our equilibrium constant. So this expression basically relates our cells voltage and the concentration of our reactants and products or the ratio of the concentration. Now, notice in this equation we have R is our constant and F is also constant.
