For the half-life period of a first order reaction, which of the following statements is false?

Answer»

It is INDEPENDENT of initial concentration.
It is independent of temperature.
It decreases with the INTRODUCTION of a catalyst.
None of these

Solution :For a FIRST order REACTION,
`t_(1//2)=(0.693)/(k)`
therefore `t_(1//2)` depends upon k and hence it depends on temperature because RATE constant k is a function of temperature.
