3. You are monitoring air quality for your city and around noontime you measure NO₂ and NO concentration of 50 and 5 ppb, respectively. Neglecting hydrocarbons and assuming the concentrations of NO2 and NO are controlled by: NO₂ + hv → NO + O 0 +02 → 03 NO + 03 → NO₂ + 0₂ (a) (b) (c) where the reaction rate ka = 0.0027s¹ and kc = 1.53 × 10-¹4 cm³ molecule-¹s-¹. From this, please estimate the steady-state concentration of ozone (in ppb). Keep two significant figures in the answer. The molar volume is 23.6 L/mol.

Question
Transcribed Image Text:3. You are monitoring air quality for your city and around noontime you measure NO₂ and NO
concentration of 50 and 5 ppb, respectively. Neglecting hydrocarbons and assuming the
concentrations of NO2 and NO are controlled by:
NO₂ + hv → NO + O
0 +02 → 03
NO + 03 → NO₂ + 0₂
(a)
(b)
(c)
where the reaction rate ka = 0.0027s¹ and kc = 1.53 × 10-¹4 cm³ molecule-¹s-¹. From this,
please estimate the steady-state concentration of ozone (in ppb). Keep two significant figures in
the answer. The molar volume is 23.6 L/mol.
