For change in entropy for change in temperature, why does it use R when the equation for delta S change in temp is delta S=nClnT2/T1?

C can be substituted with Cv=(3/2)R or Cp=(5/2)R if the substance in question is an ideal gas.

I also noticed this in the solution manual. I believe its a mistake. It should be written the way you have it. Since the volume is constant for that part of the problem, we would use the Cv value of 3/2*R in that equation
