Suppose 50 bacteria are placed in a flask containing nutrients, so that they can multiply. A study at $35^\circ$C gave the following results:
This multiplication of bacteria follows:
| Time (in minutes) | 0 | 15 | 30 | 45 | 60 |
|---|---|---|---|---|---|
| Number of bacteria | 100 | 200 | 400 | 800 | 1600 |
- (a)Zero order reaction
- (b)First order reaction
- (c)Second order reaction
- (d)Third order reaction
Answer
Answer
AICorrect option: (b)
Answer: (b) First order reaction
The number of bacteria doubles in every equal interval of 15 minutes, i.e. a constant half-life, which is characteristic of a first order reaction.
