MCQ Solution: Chemical Kinetics
Half life of radium is 1580 years. Its average life will be
1) 1.832×103 yrs
2) 2.25×103 yrs
3) 2.275×103 yrs
4) 8.825×102 yrs
Solution
t 1/2 = 0.693 / λ
∴ = 0.693 / 1580
Average life = 1 / λ = 1580 /0.693 = 2.275× 103 yrs
∴ = 0.693 / 1580
Average life = 1 / λ = 1580 /0.693 = 2.275× 103 yrs
