Units of rate constant of first and zero order reactions in terms of molarity `M` are respectively:

Options

A. `s^(-1), ML^(-1)s^(-1)`
B. `s^(-1)M`
C. `Ms^(-1), s^(-1)`
D. `M, s^(-1)`

Answer

A

Explanation

`k=(dx)/(dt[A])` for I order, unit `=sec^(-1) rArr k=(dx)/(dt)` for zero order, unit = Mol `"litre"^(-1)sec^(-1)`
