The rate constant for a zero order reaction in A is `0.0030 mol L^(-1)s^(-1).` How long it will take for the initial concentration of A to fall from 0.10 M to `0.075M.`

Explanation

In case of zero order reaction
`k=1/t [[A_(0)]-[A]]`
`{:([A]_(0)="Initial concentration"),([A]="concentration after time t"),(k=0.0030mol L^(-1)s^(-1)):}|{:([A]_(0)=0.10M),([A]=0.075M),(0.0030=1/t[0.10-0.075]),(t=(0.025)/(0.0030)=8.33"seconds."):}`
