Question

The Cp,m of liquid and solid water in the -10 °C to 0 °C range is 76.065 J mol-1 K-1 and 37.656 J mol-1 K-1, respectively. For water at -10°C and 1.0 atm, ΔSfreeze = -20.56 J mol-1 K-1. Solve for the free energy change (ΔG) when 59.8g of supercooled water freezes at 1.00 atm and a) 0 °C J b) -10 °C J

The Cp.m of liquid and solid water in the -10 °C to o °C range is 76.065 J mol1 k-1 and 37.656 J mol1 K-1, respectively. For water at -10°C and 1.0 atm, AStreeze- -20.56 J mol-1 Solve for the free energy change (AG) when 59.8g of supercooled water freezes at 1.00 atm and a)0°C b) -10 °C Hints: Use the Chapter 2 data tables and set up a thermodynamic cycle for part b.
