Show that for a first order reaction , the time taken to reach 75% of completion is about double that required for 50% of completion.

For a first order reaction , show that time required for 99% completion is twice the time required for the completion of 90% of reaction.

A first order reaction takes 60 minutes for 75% completion. Determine its half- life.

The time for half life of a first order reaction is 1 hr. what is the time taken for 87.5% completion of the reaction?

For a first order reaction the ratio of times to complete 99.9% and half of the reaction is

A first order reaction takes 30 minutes for 50% completion. Calculate the time required for 90% completion of this reaction . (log2=0.3010)

Show that for any first order reaction, the time required for the completion of 99.9% of the reaction is 10times the half-life of the reaction.

Why does a first order reaction never reach completion ?

The half -life of a first order reaction is 40min . Calculate the time taken by the reaction to reach 78% of completion . If the initial concentration of the reactant is doubled , how long will it take to reach 50% completion . Justify your answer.

Show that in a first order reaction, time required for completion of 99.9% is 10 times of half-life (t_1/2) of the reaction

The time taken by a first order reaction to reach 10% completion at 298K is the same as the time taken to reach 30% completion at 308K . If value of A=4xx10^(11)s^(-1) , calculate the rate constant at 308K.
