Nitrification is a biological process for removing NH3 from wastewater as NH4*: NH4+202NO3 + 2H + H₂O The first-order rate constant is given as k₁ = 0.47e0.095(T-15°C) -1 where k is in day and I is in °C. If the initial concentration of NH3 is 3.0 mol/m³, how long will it take to reduce the concentration to 0.80 mol/m³: (a) in the spring (T= 20°C)? days (b) in the winter (T= 10°C)? days Prex

Question
### Nitrification Process for Removing Ammonia from Wastewater

**Nitrification** is a biological process used to remove ammonia (NH₃) from wastewater by converting it to ammonium (NH₄⁺). The chemical reaction involved in this process is as follows:

\[ \text{NH}_4^+ + 2\text{O}_2 \rightarrow \text{NO}_3^- + 2\text{H}^+ + \text{H}_2\text{O} \]

The first-order rate constant \(k_1\) for this reaction is given by the equation:

\[ k_1 = 0.47e^{0.095(T - 15^\circ\text{C})} \]

where \(k_1\) is in day⁻¹ and T is in °C.

If the initial concentration of NH₃ is 3.0 mol/m³, determine the time required to reduce the concentration to 0.80 mol/m³ under different temperature conditions.

**Questions:**

(a) **In the spring (T = 20°C)?**

- Input Box for Answer: \[ \boxed{\text{days}} \]

(b) **In the winter (T = 10°C)?**

- Input Box for Answer: \[ \boxed{\text{days}} \]
