Consider the following reaction:
CaCO3(s)_CaO(s)+CO2(g).
Estimate _G_ for this reaction at each of the following temperatures. (Assume that _H_ and _S_ do not change too much within the given temperature range.)
300K
1000K
1440K

The only thing you need to do to solve this task is to find :ΔS° and ΔH°
After that, just use this formula:

 ΔG=ΔH°−TΔS°
Just calculate all of them, you have all the index.
