As learnt in

Zero Order Reaction -

Zero order reaction means that the rate of the reaction is proportional to zeroth power of the concentration of reactants

 

- wherein

R\rightarrow P

Rate=\frac{-d(R)}{dt}=K[R]^{0}=K

t_\frac {1}{2}= time required for half completion of reaction=\frac{a}{2k}

 

 

R \longrightarrow P

Rate, R = \frac{-d(R)}{dt}=k(R)^{o}=k

\therefore Unit for rate constant is Ms^{-1} or mol\;L^{-1}s^{-1}

 


Option 1)

mol L-1  s-1

This option is correct.

Option 2)

L mol-1  s-1

This option is incorrect.

Option 3)

L2 mol-2  s-1

This option is incorrect.

Option 4)

s-1

This option is incorrect.
