The mechanism of the reaction $2NO_2 + F_2 \to 2NO_2F$ is

$(i)\,\,N{O_2}\,\xrightarrow{{slow}}\,NO + O$

$(ii)\,\,{F_2} + O + NO\,\xrightarrow{{fast}}\,N{O_2}F + F$

$(iii)\,\,F + N{O_2}\,\xrightarrow{{fast}}\,N{O_2}F$

Select the correct one

In a reaction, $2X \to Y$ , the concentration of $X$ decreases from $0.50\, M$ to $0.38\, M$ in $10\, min$ . what is the rate of reaction in $Ms^{-1}$ during the interval ?

For the following reaction scheme (homogeneous), the rate constant has units

$A+B\xrightarrow{K}C$:

The reaction $CH _{3} COF + H _{2} O \quad \rightleftharpoons CH _{3} COOH + HF$

Condition $I$ $:$ $\left[ H _{2} O \right]_{0}=1.00 \,M$

                           $\left[ CH _{3} COF \right]_{0}=0.01 \,M$

Condition $II$ $:$ $\left[ H _{2} O \right]_{0}=0.02 \,M$

                             $\left[ CH _{3} COF \right]_{0}=0.80 \,M$

Determine the order of reaction and calculate rate constant.

Write differential rate expression of following reaction and give its order of reaction :

$H _{2} O _{2}+ I ^{-} \rightarrow H _{2} O + IO ^{-}$

$H _{2} O _{2}+ IO ^{-} \rightarrow H _{2} O + I ^{-}+ O _{2}$

For a reaction $A+ B\to $  Products, the rate law is - Rate $=$ $k\,[A]\, [B]^{\frac {3}{2}}$ . Can the reaction be an elementary reaction ? Explain.
