PLEASE HELP! ANY HELP IS MUCH APPRECIATED!!

1. Calculate the equilibrium constant at 20 K for a reaction with ?Ho = 10 kJ and ?So = (-100) J/K. (Don't round unil the end. Using the exponent enlarges any round-off error.)

2. Calculate the equilibrium constant at 118 K for the thermodynamic data in the previous question. (#1)

3. Calculate the equilibrium constant at 29 K for a reaction with ?Ho = 10 kJ and ?So = 100 J/K.

4. Calculate the equilibrium constant at 110 K for the thermodynamic data in the previous question. (#3)

5. Calculate ?G (in kJ) at 65 oC for the reaction:

N2O(0.0070 atm) + H2(0.32 atm) ? N2(183.8 atm) +H2O(l)

6. Assume that the ?Ho and ?So of vaporization do not change significantly with temperature. Calculate the vapor pressure of CH3OH at 67 oC (in atm).

CH3OH (l) ? CH3OH(g) . . . ?Ho = 38.0 kJ and ?So = 112.9 J/K

(Don't round unil the end. Using the exponent enlarges any round-off error.) Hint given in feedback.

7. Calculate the vapor pressure of Hg at 37 oC (in atm).

Hg(l) ? Hg(g) . . . ?Ho = 61.32 kJ and ?So = 98.83 J/K

Explanation / Answer

use the formula

delta G= -RTln K

K=(partial pressure of N2* partial pr of HO2)/(partial pr of N2O*partial pr of H2)

R=8.314J
