Correct answer: A. 44.5 days
- A. 44.5 days
- B. 1.3 million years
- C. 3.8 days
- D. 2.5 billion years
Explanation
The isotope of tron with mass number 59 (59 F'e) has a half-life of approximately 44.5 days. This means it takes 44.5 days for half of the radioactive 59Fe atoms in a sample to decay.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
