Question
Consider the following first order decomposition and the accompanying concentration ñ time plot: 
(log 2 = 0.3, log 5 =0.7)
- At 30 hrs , only 20 %reaction iscomplete.
- Half -life of the reaction is 90 hrs(approximately).
- Rate of decomposition decreases linearly withtime.
- Changing initial concentration will change the time at which the two curves areintersecting
The correct answer is: Half -life of the reaction is 90 hrs(approximately).
