The half-life of 2nd order of reaction is:
Correct answer: B. t1/2 = 1 / k[A]
- A. t1/2 = ln(2) / k
- B. t1/2 = 1 / k[A]
- C. t1/2 = 1 / k[A]²
- D. None of these
Explanation
Option B is correct.This is for second order.of reaction.For Second order rate = k[A]². We know that half live= t1/2 =1/a ,t1/2 = 1 / k[A] .

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.

A radioactive element has two isotopes, "G" and "H", with half lives of 5 min and 15 min respectively. An experiment starts with 4 times as many atoms of "G" as of "H". Radioactive decay is a first order reaction. how long will it be before the number of atoms of "G" left equal the number of atoms of "H" left?
