The molar entropy of CO2 at ambient conditions is Sm 214 J

The molar entropy of CO2 at ambient conditions is Sm = 214 J K-1 mol-1. For the amount of n = 3.50 mol of CO2, determine the change in temperature T needed to decrease the Gibbs energy G by 24.8 kJ at constant pressure.

Solution

the change in temepratire is calculated as follows:

     [214 J K-1 mol-1][3.50 mol][dT] = 24.8X10^3 J

therefore, dT = 33.11 K
