Delta H
For the reaction : 3NO (g) --> N2O (g) + NO2 (g)

Calculate the Gibbs energy of the reaction (delta G rxn) at 25'C for the above rxn when all three gases are at 0.0010 atm. Kp = 1.8 x 10 ^ - 18

Using the following data for the reaction of Hydrogen with carbon dioxide to give formic acid (methanoic acid) at 298.15K, calculate delta H, delta S, delta G for the vaporization of liquid formic at 298.15 K.

(kJmol^-1) ( kJmol^-1)

H2(g) + CO2 (g) ---> HCOOH (g) + 30.9 +58.6
H2 (g) + CO2(g) -----> HCOOH (l) -31.2 +32.9
