In the reaction A→2B , the concentration of A falls from 1.0M to 0.88M in one minute what is the rate in moles litre−1sec−1

For the reaction A→2B Given,[A]=1.0M  to 0.88M Time= 1 minuteRate=?rate=dCdt Where,dC = Change in concentrationdt= time taken for the changerate=(1−0.88)1 mint rate=0.1260 =15×10−2 =2×10−3
