Time requires for 99% completion of a first order reaction is twice to that required for 90% completion of the same reaction. Explain.

Time required for 50% completion of the first order reaction in one hr. What is the time required for 99% completion of the same reaction ?

The time required for 10% completion of a first order reaction at 298K is equal to that required for its 25% completion at 308K . If the value of A is 4xx10^(10)s^(-1) , calculate k at 318K and E_(a) .

Show that the time required for the completion of 75% of a reaction of first order is twice the time required for the completion of 50% of the reaction.

Half life time for first order reaction is 25 minutes . What time will be required for 99% completion of reaction ?

In the case of a first order reaction, the ratio of time required for 99.9% completion to 50% completion is

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 :

The time of completion of 90% of a first order reaction is approximately
