Question

Consider the decomposition reaction shown below.


NO2(g) ⇄ NO(g) + ½ O2(g)

Temperature is 25 °C. ΔG°rxn is +34.85 kJ/mol

Assuming the reaction takes place in a closed vessel with an initial NO2(g) pressure of 2.540 atm, what 
are the partial pressures of each of the gases at equilibrium? Show a complete ICE table. Indicate any 
assumptions that you made in your calculations.
