${\mathrm{H}}^{+}$ catalysed hydrolysis of ester ${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5+{\mathrm{H}}_2\mathrm{O}\stackrel{ {\mathrm{H}}^{+} }{\to }{\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$ is a pseudo unimolecular reaction. Explain.

What are pseudo unimolecular reactions? Explain with the help of a suitable example.

What is pseudo first order reaction? Give an example of it. 

Why hydrolysis of ethyl acetate with NaOH is reaction of second order while with HCl, it is of first order?

State any one condition under which a bimolecular reaction may be kinetically of first order.

For a reaction, $\mathrm{A}+{\mathrm{H}}_2\mathrm{O}\stackrel{ }{\to }\mathrm{B}$, $\mathrm{rate}\propto \left[\mathrm{A}\right]$. What is its order of reaction?
 

For a reaction $\mathrm{A}+\mathrm{B}⟶\mathrm{P}$, the rate is given by Rate $=\mathrm{k}[ \mathrm{A}][\mathrm{B}{]}^2$.

What is the overall order of reaction if $\mathrm{A}$ is present in large excess ?

For a reaction, $\mathrm{A}+{\mathrm{H}}_2\mathrm{O}\stackrel{ }{\to }\mathrm{B}$, $\mathrm{rate}\propto \left[\mathrm{A}\right]$. What is its molecularity?
 

The rate constant for a second order reaction is $\mathrm{k}=\frac{2.303}{\mathrm{t}\left(\mathrm{a}-\mathrm{b}\right)}\log \frac{\mathrm{b}\left(\mathrm{a}-\mathrm{x}\right)}{\mathrm{a}\left(\mathrm{b}-\mathrm{x}\right)}$ where $\mathrm{a}$ and $\mathrm{b}$ are initial concentrations of the two reactants $\mathrm{A}$ and $\mathrm{B}$ involved. If one of the reactants is present in excess, it becomes pseudo unimolecular. Explain how?

In the hydrolysis of an ester in presence of large excess of water. The order of the reaction is 

For the hydrolysis of esters in alkaline medium rate expression is :$-\frac{\mathrm{d}\left[\mathrm{Ester}\right]}{\mathrm{dt}}=$ $\mathrm{K}\left[\mathrm{Ester}\right]\left[\mathrm{Alkali}\right]$ In case alkali used is in excess, then the overall order of the reaction is :

The acid catalyzed iodination of propanone represented by equation :

${\mathrm{CH}}_3{\mathrm{COCH}}_3+{\mathrm{I}}_2\stackrel{\left[{\mathrm{H}}^{+}\right]}{⟶}{\mathrm{CH}}_3{\mathrm{COCH}}_2\mathrm{I}+\mathrm{HI}$

is first order w.r.t. ${\mathrm{H}}^{+}$ ion and to propanone and zero order w.r.t. ${\mathrm{I}}_2$. Then correct graph between rate of reaction $\left[\mathrm{R}\right]$ vs $[\mathrm{CH}$$\left.{}_3\mathrm{COCH}_3\right]$
