In a certain patient, it has a first-order half-life in the blood of 3.9 min. To maintain an adequate blood concentration of insulin, it must be replenished in a time interval equal to 1/k. How long is the time interval in this patient? min

Answer 1

Answer -

Given,

Half life = 3.9 min

Replenished time = 1/k

Replenished time in min = ?

We know that,

Half life = 0.692/rate constant k

Half life/0.692 = 1/ k ----------------A

And,

Replenished time = 1/k ------------------B

From A and B

Replenished time = Half life / 0.692

Put the value,

Replenished time = 3.9 min / 0.693

Replenished time = 5.63 min [Answer]
