Question 2

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 N₂O₄(g) will decompose into NO₂(g).
◦ Some NO₂(g) will dimerize to form N₂O₄(g).
◦ The system is at equilibrium at these initial pressures.
◦ The final total pressure must be known to answer this question.
◦ None of these are correct.
