Question

The rate of constant of a chemical reaction has units L mol-1 s-1. Order of the reaction will be (A) 0 order (B) 1st order (C) 2nd order (D) 3rd order

Tardigrade Admin · Accepted Answer

For a 2nd order reaction k=(Rate/(conc)2)=(mol L-1s-1/(mol L-1)2) =mol-1 L s-1

Q. The rate of constant of a chemical reaction has units $L m o l^{- 1} s^{- 1}$ . Order of the reaction will be

0 order

1st order

2nd order

3rd order

For a 2nd order reaction
$k = \frac{R a t e}{( co n c ) ^{2}} = \frac{m o l L ^{- 1} s ^{- 1}}{( m o l L ^{- 1} ) ^{2}}$
$= m o l^{- 1} L s^{- 1}$

Q. The rate of constant of a chemical reaction has units Lmol−1s−1. Order of the reaction will be
