What is the unit of rate constant for a zero order reaction?

mole L-1 s-1 s-1 mole-1 L s-1 None of these

mole L-1 s-1

Unit of rate constant = (mole)1-n (L)n-1 time-1 ,   where n= order of reaction if n = 0 i.e. for zero order reaction, the unit of rate constant will be (mole)1-0 (L)0-1 s-1 = mole L-1 s-1
