The rate constant of esterification $(k) = k'\, [H_2O]$ rate constant of esterification $2.0\times 10^{-3}\,min^{-1}$ calculate $k'$.
$k=k^{\prime}\left[\mathrm{H}_{2} \mathrm{O}\right]$
$\begin{aligned} \therefore k^{\prime} =\frac{k}{\left[\mathrm{H}_{2} \mathrm{O}\right]}=\frac{2.0 \times 10^{-3} \mathrm{~min}^{-1}}{55.5 \mathrm{~mol} \mathrm{~L}^{-1}} \\ =0.036 \times 10^{-3} \mathrm{~mol}^{-1} \mathrm{~L} \mathrm{~min}^{-1} \\ =3.6 \times 10^{-5} \mathrm{~mol}^{-1} \mathrm{~L} \mathrm{~min}^{-1} \end{aligned}$
During Kinetic study of reaction $2 A+B \rightarrow C+D$, the following results were obtained :
$A[M]$ | $B[M]$ |
initial rate of formation of $D$ |
|
$i$ | $0.1$ | $0.1$ | $6.0 \times 10^{-3}$ |
$ii$ | $0.3$ | $0.2$ | $7.2 \times 10^{-2}$ |
$ii$ | $0.3$ | $0.4$ | $2.88 \times 10^{-1}$ |
$iv$ | $0.4$ | $0.1$ | $2.40 \times 10^{-2}$ |
Based on above data, overall order of the reaction is $\qquad$
If the concentration of the reactants is increased, the rate of reaction
The concentration of $R$ in the reaction $R \rightarrow P$ was measured as a function of time and the following data is obtained:
$[R]$ (molar) | $1.0$ | $0.75$ | $0.40$ | $0.10$ |
$\mathrm{t}$ (min.) | $0.0$ | $0.05$ | $0.12$ | $0.18$ |
The order of the reaction is
For reaction :
$2NO_2(g) + O_3(g) \to N_2O_5(g) + O_2(g)$
rate law is $R = K\, [NO_2]' [O_3]'$.
Which of these possible reaction mechanisms is consistent with the rate law?
Mechanism $I :$
$NO_2(g) + O_3(g) \to NO_3(g) + O_2(g)$ (slow)
$NO_3(g) + NO_2(g) \to N_2O_5(g)$ (fast)
Mechanism $II :$
$O_3(g) \rightleftharpoons O_2(g) + [O]$ (fast)
$NO_2(g) + [O] \to NO_3$ (slow)
$NO_3(g) + NO_2(g) \to N_2O_5$ (fast)
The reaction between $A$ and $B$ is first order with respect to $A$ and zero order with respect to $B$. Fill in the blanks in the following table:
