In some aquatic ecosystems, nitrate (NO3-) is converted to nitrite (NO2-), which then decomposes to nitrogen and water. As an example of this second reaction, consider the decomposition of ammonium nitrite:
NH4NO2 (aq) → N2 (g) + 2H2 O (l)
What would be the change in pressure in a sealed 10.0 L vessel due to the formation of N 2 gas when the ammonium nitrite in 2.40 L of 1.340 M NH4NO2 decomposes at 25 °C?
