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:
Time (in minutes)015304560
Number of bacteria1002004008001600
This multiplication of bacteria follows:
  • (a)Zero order reaction
  • (b)First order reaction
  • (c)Second order reaction
  • (d)Third order reaction

Answer

Correct 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.
