For a chemical reaction $A \rightarrow B$, it was found that concentration of $B$ is increased by $0.2\, mol\,L^{-1}$ in $30\, \mathrm{~min}$. The average rate of the reaction is $......\times 10^{-1} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~h}^{-1}$. (Nearest integer)

Which one of the following statements is wrong

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.

Assertion : The kinetics of the reaction -

$mA + nB + pC \to m' X + n 'Y + p 'Z$

obey the rate expression as $\frac{{dX}}{{dt}} = k{[A]^m}{[B]^n}$.

Reason : The rate of the reaction does not depend upon the concentration of $C$.

Write unit of rate constant of following reaction :

$1.$ $\frac {5}{2}$ order

$2.$  $n$ order

In the following reaction $A \to B + C$, rate constant is $0.001\, M/sec$. If we start with $1M$ of $A$, the conc. of $A$ & $B$ after $10$ min are respectively
