So for this given reaction, what we're looking to do is calculate gibbs free energy, where we have delta g is equal to delta g0, which is the change in standard free energy, add rtlnq, the reaction quotient, temperature, and the r gas constant.
00:22
So what we can do is plug in values that we have for delta g0, which is equal to the sum of the moles multiplied by, the change in gibbs free energy of formation of the products, subtract the sum of the moles multiplied by the change in gibbs free energy of formation of the reactants.
00:45
And so what we find for this is we have 51 .94 kilojoules per mole.
00:55
And so where our r is the universal gas constant and t is the temperature, but we do need to use kelvin.
01:01
So we can take 37 degrees celsius to that we add 27.
01:05
To give us 310 kelvin for our temperature, where q is our reaction quotient, which we are given...
