Use the following information to answer the next question. Dinitrogen tetraoxide was used as one of the rocket fuels on the lunar landers of the Apollo missions. In the gaseous phase, it decomposes according to the following equation. N₂O4(g) 2 NO₂(g) AH° = +55.3 kJ A technician placed a sample of N₂O4(g) in a 2.00 L flask and allowed the system to reach equilibrium. At 25 °C, the K, was 5.40 x 10³, and the concentration of N₂O(g) at equilibrium was 3.00 x 10¹ mol/L. 2. a. Determine the amount, in moles, of NO2 (g) present in the 2.00 L flask at equilibrium. (Value: 2 pts) b. Identify whether the value of Ke will increase, decrease, or remain the same when heat is added to the system. Support your answer with an explanation. (Value: 3 pts)
