If a first order reaction takes 32 minutes for 75% completion, then time required for `50%` completion is :

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

A first order reaction takes 69.3 minutes for 50% completion. Calculate time required for 80% completion of the reaction.

A first order reaction takes 69.3 minutes for 50% completion. Calculate the time required for 80% completion of the reaction.

A first order reaction takes 30 minutes for 50 % completion. Calculate the time required for 90 % 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 :

A first order reaction taken 32 minutes for 50% completion. Hew much time will it take for 90% completion ?

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