Standard of DSC:
How DSC can be used for measuring the heat capacity of solid samples. Is a particular standard required?
Answer:
In an enthalpogram represents primarily change in enthalpy and temperature due to the titration reaction. However, it also involves internal heat evolved or absorbed.
As per eq. (11.20) RT ln K = - ? H + T.? S which as rearrangement gives
?S = RT ln K+?H/T =R ln K+?H/T
