L mol-1 s-1 According to second order reaction 2Aarrow Product rate of reaction -(d[A]/dt) propto [A]2 or (dA/dt)=k[A]2 k= Reaction rate constant then unit of second order reaction rate constant k=-(d[A]/dt)× (1/[A]2) =(1/s.mol L-1) or L mol-1s-1

Q. The unit of second order reaction rate constant is:

$L^{- 1} .$ mol. $s^{- 1}$

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

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

$s^{- 1}$

Q. The unit of second order reaction rate constant is:

L−1. mol. s−1

L2.mol−2.s−1

L.mol.s−1 .

s−1

Lmol−1s−1 According to second order reaction 2A→ Product rate of reaction −dtd[A]​∝[A]2 or dtdA​=k[A]2 k= Reaction rate constant then unit of second order reaction rate constant k=−dtd[A]​×[A]21​ =s.molL−11​ or Lmol−1s−1

$L^{- 1} .$ mol. $s^{- 1}$

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

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

$s^{- 1}$
