The half life period 't' of a zero order reaction as shown in the bellow figure, is equal to_________________?
Correct answer: A. CA0/2K
- A. CA0/2K
- B. CA0/K
- C. 0.693/K
- D. 1/K
Explanation
For a zero-order reaction, the concentration relation is C_A=C_A0−kt. Setting C_A=C_A0/2 gives t_1/2=C_A0/(2k), unlike a first-order half-life, which is independent of initial concentration.
