Question

The units of rate constant for first order reaction are (A)  mol L-1s-1  (B)  s-1  (C)  L mol-1s-1  (D)  L2mol-2s-1

Tardigrade Admin · Accepted Answer

For nth order reaction, the units of rate constant = (mol L-1)1-n . s-1. (where, n = order of reaction) ∴ For first order reaction, the units of rate constant= (mol L-1)1-1 . s-1 = s-1

Q. The units of rate constant for first order reaction are

$m o l L^{- 1} s^{- 1}$

$s^{- 1}$

$L m o l^{- 1} s^{- 1}$

$L^{2} m o l^{- 2} s^{- 1}$

For nth order reaction,

the units of rate constant = $(m o l L^{- 1})^{1 - n} . s^{- 1} .$

(where, n = order of reaction)

$∴$ For first order reaction,

the units of rate constant= $(m o l L^{- 1})^{1 - 1} . s^{- 1} = s^{- 1}$

Q. The units of rate constant for first order reaction are

molL−1s−1

s−1

Lmol−1s−1

L2mol−2s−1

For nth order reaction, the units of rate constant = (molL−1)1−n.s−1. (where, n = order of reaction) ∴ For first order reaction, the units of rate constant= (molL−1)1−1.s−1=s−1

$m o l L^{- 1} s^{- 1}$

$s^{- 1}$

$L m o l^{- 1} s^{- 1}$

$L^{2} m o l^{- 2} s^{- 1}$

For nth order reaction,

the units of rate constant = $(m o l L^{- 1})^{1 - n} . s^{- 1} .$

(where, n = order of reaction)

$∴$ For first order reaction,

the units of rate constant= $(m o l L^{- 1})^{1 - 1} . s^{- 1} = s^{- 1}$
