Dinitrogen tetroxide decomposes to nitrogen dioxide:
N2O4 (g) ---> 2NO2 (g) Delta H rxn: 55.3 kJ
At 298 K a reaction vessel initially containing .100 atm of N2O4. When equilibrium is reached, 58% of the N2O4 has decomposed to NO2.
-What percentage of N2O4 decomposes at 350 K? Assume that the initial pressure of N2O4 is .100 atm.
