And to see what we mean by that, let's carry out the following calculation. So, in this particular case, we know that Delta G standard state condition is equal to 21.3 kilojoules. Now, the question is what exactly should the Q value be for this Delta G to actually be negative and for our reaction to be spontaneous product favorite. 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.
