In a second order reaction, `20%` of a substance is dissociated in `40 min`. The time taken by `80%` of its dissociation is

If 50% of a radioactive substance dissociates in 15 min, then the time taken by substance to dissociate 99% will be

A first order reaction is 20% complete in 10 minutes. Calculate the time taken by the reaction for 75% completion?

The initial concentration of both the reactants of a second order reaction are equal and 60% of the reaction gets completed in 30s . How much time will be taken in 20% completion of the reaction?

The initial concentration of both the reactants of a second order reaction are equal and 60% of the reaction gets completed in 30s . How much time will be taken in 20% completion of the reaction?

A first order reaction takes 69.3 min for 50% completion. The time required for 80% completion of this reaction is :

40% of a first order reaction is completed in 50 minutes. How much time will it take for the completion of 80% of this reaction?
