Question

Units of rate constant for first and zero order reactions in terms of molarity M unit are respectively (A) M sec-1, sec-1 (B) M sec-1 (C) sec-1, M sec-1 (D) sec-1, M

Unit of rate constant =[(1/M)]n-1 time-1 for zero order, [(1/M)]-1 sec-1=M sec-1 for first order , [(1/M)]1-1 sec-1=sec-1

Q. Units of rate constant for first and zero order reactions in terms of molarity $M$ unit are respectively

$M se c^{- 1}, se c^{- 1}$

$M se c^{- 1}$

$se c^{- 1}, M se c^{- 1}$

$se c^{- 1}, M$

Unit of rate constant $= [\frac{1}{M}]^{n - 1} t im e^{- 1}$
for zero order, $[\frac{1}{M}]^{- 1} se c^{- 1} = M se c^{- 1}$
for first order , $[\frac{1}{M}]^{1 - 1} se c^{- 1} = se c^{- 1}$
