Time for half change for a first order reaction is 25 min. What time will be required for 99% reaction ?

 t 2 = 2t 1 because for 3/4th of the reaction to complete time required is equal to two half lives

The answer is 30 mins

First order reaction.

t2 = 2t1 because for 3/4th of the reaction to complete time required is equal to two half lives.

The answer is 30 mins.

The answer is 6.25%

Give explanation plz

The correct answer is  "TWO"

According to the given reaction: Rate = k [A] [B]2 (i) When the concentration of reactant ‘B’ is increased three times the rate of reaction becomes 9 times. i.e., Rate = k [A]...
