Calculate k calculate also how long it would take for half, Ask an Expert

Academics

The reaction: CH3CH2NO2+OH- --> H2O+CH3CHNO2- obeys the rate law d[A]/dt=-k[A][OH-], where A denotes CH3CH2NO2. It takes 0.5 min for one percent of the A to react at 25C, in the case of a solution 0.002M in A and 0.3M in NaOH. Calculate k. Calculate also how long it would take for half of A to react. **HINT: assume pseudo first order with k'=k[OH-], since [OH-] is in great excess.
