Homework Help: Chemistry

Posted by Anonymous on Wednesday, April 3, 2013 at 2:44pm.

At 298 K, deltaGo = - 6.36 kJ for the reaction:

2N2O(g) + 3O2(g) ↔ 2N2O4(g)

Calculate deltaG (in kJ) at 298 K when PN2O = 3.12 atm, PO2 = 0.0081 atm, and PN2O4= 0.515



Calculate deltaG (in kJ) at 298 K for some solid ZnF2, 0.025 M Zn2+ and 0.038 M F-(aq).

Would these two be done in the same way, and if so, how?

Also, how do you find the vapor pressure of given the temperature, delta h, and delta s?

For example:
Calculate the vapor pressure of Hg at 14 oC (in ATM)

Hg(l) deltaHg(g) . . . deltaHo = 61.32 kJ and deltSo = 98.83 J/K

Thank you!
