(1) Determine the final state of the system (ice or liquid water) with temperature.

(3) Calculate △S for water.

(4) Calculate the overall △S for the process to determine the process is spontaneous or nor.

(2) Calculate g(heat), w(work), △U (change in internal energy) and △H (change in enthalpy) for the process.

(2) Find the activity coefficient of each component Please take the pure substance as the standard state for cach component.

(1) Find the activity of each component

(2) Find the activity coefficient of each component Please take the pure substance as the standard state for each component.

5. Please write the equation that relates the temperature to the amount of gas adsorbed on a solid's surface, and solve for enthalpy change for the adsorption of 40 cm³of CO (measured at 0 ℃ and 1 atm) by 1 g of silica at 60 °K, and 8 cm³ at 298 °K.

6. Given that Henry's law constant for the solubility of oxygen gas in water is 3.30 x 10⁷ torr at 25℃, please calculate the solubility of oxygen under room temperature. Consider air to be 20% O₂ at room temperature.

7. The rate of a first order reaction increases from 1.5 x to at 260 ℃ when a catalyst is added to the reaction. Calculate the decrease in the activation enthalpy H, assuming S°, the activation entropy, is not affected by the catalyst.
