Question
A chemical breaks down in a flow-balanced, steady-state CFMR according to first-order reaction kinetics. At steady state, the upstream and downstream concentration of the chemical are 15 mg/L and 5 g/m3. Water is being treated at a rate of 0.42 m3/sec. The volume of the tank is 500,000 liters. Assuming a first-order reaction, what is the rate constant

Answer:
Explanation:
From the given information:
The initial concentration of a chemical
The final concentration is
= 5 mg/L
Volume flow rate
Volume of the tank V = 500 000 L = 500 m³
The time t is determined by using the formula:
t = 1190.47 sec
t ≅ 19.8 min
∴
The rate of the decay constant is:
