If the rate constant $(K)$ of a reaction is $1.6 \times 10^{-3}\, mol\, L^{-1}\, min^{-1}$ the order of reaction is

Following is the rate constant of reaction what is the overall order of reaction ?

$(a)$ $2.1 \times 10^{-2}\,mol \,L ^{-1} \,s ^{-1}$

$(b)$ $4.5 \times 10^{-3} \,min ^{-1}$

For $n^{th}$ order reaction where $(n < 1)$

Select the incorrect option :

$n$ presence of $HCl$, sucrose gets hydrolysed into glucose and fructose. The concentration of sucrose was found to reduce form $0.4\,M $ to $0.2 \,M$  in $1$  hour and $0.1 \,M $ in $2$ hours. The order of the reaction is

 Which of the following optioms correctly represents relationship between $t_{7/8}$ and $t_{1/2}$ where $t_{7/8}$ represent time required for concentration to become $\frac{1}{8} \,th$ of original for  a reaction of order $'n'$
