Question

What is the reaction constant if the initial concentration of a contaminant is 100 mg/L, and its final concentration is 10 mg/L after a period of 2 hours and the reaction is characterized bya) Zero Order Kinetics

Answer 1

the reaction constant will be k = 45 mg/(L*h)

Step-by-step explanation:

if the reaction follows a zero order kinetics , then the reaction rate is independent of the concentration and remains constant = k. Then we can take any changes in the concentration to calculate the reaction constant k

k = (final concentration - initial concentration)/ Time = (100 mg/L- 10 mg/L)/ 2 hours = 45 mg/(L*h)

k = 45 mg/(L*h)
