Consider the reaction 2NO2(g) N2O4(g); ΔH° = –56.8 kJ and ΔS° = –175 J/K. In a container (at 298 K) N2O4(g) and NO2(g) are mixed with initial partial pressures of 2.4 atm and 0.42 atm, respectively. Which of the following statements is correct? Some NO2(g) will dimerize to form N2O4(g). Some N2O4(g) will decompose into NO2(g). The final total pressure must be known to answer this question. The system is at equilibrium at these initial pressures. None of these choices are correct.
