Question

Units of specific reaction rate for $2^{nd }$ order reaction is

• A. $s ^{-1}$
• B. $mol \,L ^{-1} \,s ^{-1}$
• C. $L ^{2} \,mol ^{-2} \,s ^{-1}$
• D. $L \,mol ^{-1} \,s ^{-1}$

Answer 1

Answer: (D)

Units of specific reaction rate of $nth$ order reaction are

$k=\left( mol\, L ^{-1}\right)^{1-n} \,s ^{-1}$

For $2^{nd}$ order, $k= L \,mol ^{-1} \,s ^{-1}$
