If the rate constant for a first order reaction is k, the time (t) required for the completion of 99% of the reaction is given by :

If the rate constant for a first order reaction is k, the time (t) required for completion of 99 % of the reaction is given by

For the first order reaction, time required for 99% completion is :

For the first order reaction, time required for 99% completion is :

The half life period of a first order chemical reaction is 6.93 minutes. The time required for the completion of 99% of the reaction will be (log2=0.301)

The half life period of a first order chemical reaction is 6.93 minutes. The time required for the completion of 99% of the reaction will be (log2=0.301)

The half life period of a first order reaction is 6.93 minutes. The time required for the completion of 99% of the chemical reaction will be (log 2=0.301)

Prove that for a 1st order reaction, the time taken for 99% completion of the reaction is twice the time required for the completion of 90% of the reaction.

For a first order reaction, if the time taken for completion of 50% of the reaction is t second, the time required for completion of 99.9% of the reaction is:
