WebMar 30, 2024 · The change in Gibbs free energy is given at constant temperature as: ΔG = ΔH − T ΔS. For a given reaction with given constant temperature T in K, entropy change of the reaction ΔS ( J/mol⋅K) and enthalpy change of the reaction, ΔH (kJ/mol). From this, it can be established that reactions which have a positive ΔH and a negative ΔS are ... WebThat's negative 72 plus 32. So the temperature in Fahrenheit would equal negative 40 as well. So negative 40 degrees Celsius is the same thing as saying negative 40 degrees Fahrenheit. That's kind of just a fun fact. And another observation from this little factoid is that Celsius and Fahrenheit scales can both have negative or positive values.
