1. Calculate the molar entropy of a constant pressure sample of argon at 250 K. Given the molar entropy of this gas sample at 298 K is 154.84 J/Kmol. This argon gas is heated from 250 K to 298 K. The molar heat capacity at constant pressure of argon is 3/2 R, and this heat capacity is constant at the temperature range of interest.

2. To calculate the standard reaction entropy at 298 K of sucrose [C12H22O11(s) + 12O2(g) 12 CO2(g) + 11H2O(l). Given the standard molar entropy ( ) at 298 K for C12H22O11(s) is 360.2 J/Kmol, O2(g) is 205.138 J/Kmol, CO2(g) is 213.74 J/Kmol, and H2O(l) is 69.91 J/Kmol.
