Consider the first-order decomposition of nitramide shown below: NH₂NO₂(aq) ⇌ N₂O(g) + H₂O(l) The half-life is 123 min at 15.0 °C. If 114.0 mL of a 0.105 M NH₂NO₂ solution is allowed to decompose, how long must the reaction proceed to yield 50.0 mL of N₂O(g) collected over water at 15.0 °C and a barometric pressure of 1.01 bar? The vapour pressure of water at 15.0 °C is 1.70 x 10⁻² bar.
