Finally, we plug in all our information. So our R, it's 8.31
joules per mole times Kelvin, times natural log of 360 or 40, which is simply nine times. Now, we have to use our temperature in Kelvin, and that means we have to convert from celebrates to Kelvin by simply adding 273 to each temperature. So this is what we get. We basically plug this into our calculator. We solve, and we get approximately 44 kilojoules per mole.
