The concentration of substance X is initially 100 mg/L. The concentration is reduced to 33 mg/L in 1 hour. Ho long will it take for the concentration to be reduced to 1.0 gL if substance X reacts via zero order kinetics? 5.

Solution

Solution :-

Given

Initial concentration (X) = 100 mg/l

reaction Rate =concentration/( time )

=( 100 – 33)/ (1)

= 67 mg/(l –hour)

Time require for concentration 1 µg/l = concentration/(reaction rate)

= (100 – 0.001)/67

= 1.49 hour   

= 89.4 minutes   Answer
