And the way that we're going to solve this problem is by basically using some type of negative value for this Delta G. So let's suppose Delta G is any negative value for, so let's suppose it's negative five kilojoules. So this quantity is negative five kilojoules and this quantity is positive 21.3 kilojoules. Now, because the gas constant R is given to us in Joules, so 8.3 114 Joules per kelvin times mole, let's transform these quantities into Joules. So this quantity is equivalent to 21,300 Joules and that's a positive value. While this quantity, we said just a moment ago we're going to use negative five kilojoules, or equivalently negative 5000 Joules. Now, the goal is to ultimately calculate what the Q value has to be, what the ratio of the concentrations of the products to the reactants has to be for the reaction to actually be product favored, for this to be negative 5000 on negative value.
