Question 1

Is decay ever exactly zero?

Accepted Answer

Mathematically exponential decay approaches zero asymptotically; practically, background noise dominates.

Question 2

Does half-life change with amount?

Accepted Answer

For first-order kinetics, half-life is constant regardless of starting quantity.

Question 3

Can this model drug elimination?

Accepted Answer

Many drugs follow one-compartment models approximating exponential decline after peak concentration.
