Question

which statement is true about half life of a first order reaction

Answer 1

Answer:

The formula to calculate half life for the first order reaction is: t12=0.693k .

Hence it is a false statement. The third statement is; for a first order reaction, the half life is independent of concentration.

And it is a true statement.

Answer 2

Complete question:

The question could be incomplete. Complete question is-

Which statement is true about half life of a first order reaction?

A. The rate of reaction is directly proportional to the zero power of concentration of the reactants.

B. The unit of rate constant is mol L s

C. The half life of reaction does not depend on the initial concentration of thr reactants.

D. Cannot be said directly.

Answer:
