Yes, A is the correct answer.

Ram Meena said: 7 years ago

The half-life of a first order reaction is independent of the starting concentration.

Khalid Abed said: 8 years ago

For first order reaction t1/2 = ln 2/ k.

So, t1/2 is independent of concentration.

Yogesh Patil said: 9 years ago

I think it is Independent of initial concentration.

MKS said: 9 years ago

Half life depends upon only K.

Vipin jain said: 1 decade ago

B is not the answer because for first order reaction t1/2=0.693/k.

That means t1/2 is independent of concentration.
