4f.1

Is it incorrect to report the entropy change in Celcius rather than kelvin?

[Kevin Xu 4F]

I don't know if it is incorrect to but if the units of entropy are in Celsius, that would affect the calculations of other equations that use temperature. The temperature would have to be in C instead of K, and could produce mathematical errors if the temperature is 0 degrees Celsius (divide by zero).

I would play it safe and always stick to entropy's usual units of Joules/Kelvin. Most of the time when you use the gas constant for entropy problems, you'll be using 8.314 J/K*mol, so it would be better to keep using Kelvin for entropy! I think it's only with Calorimetry and specific heat capacities that we normally use Celsius. Hope this helps!
