Question

Calculate $\Delta$G, $\Delta$A, and $\Delta$S_univ for each of the following processes and state any approximation made:

a) reversible melting of 36.0 g of ice at 0^oC and 1 atm
b) reversible vaporization of 39 g of C₆H₆ at its normal boiling point of 80.1^oC and 1 atm
c) adiabatic expansion of 0.100 mol of a perfect gas into vacuum with initial temperature of 300 K, initial volume of 2.00 L, and final volume of 6.00 L

Densities of liquid and solid water at 300 K are 1.00 g/cm3 and 0.917 g/cm3, respectively.



Please show all work. I get confused easily if steps are skipped. Thank you!

Problem 4. Calculate AG, AA, and ASuniv for each of the following processes and state any approximation made: a) reversible melting of 36.0 g of ice at 0 °C and 1 atm; b) reversible vaporization of 39 g of CsH6 at its normal boiling point of 80.1 °C and 1 atm; c) adiabatic expansion of 0.100 mol of a perfect gas into vacuum with initial temperature of 300 K, initial volume of 2.00 L, and final volume of 6.00 L. Densities of liquid and solid water at 300 K are 1.00 g/cm3 and 0.917 g/cm3, respectively.
