- A 10 min experimental run shows that $75 \%$ of liquid reactant is converted to product by a $1 / 2$ order rate. What would be the amount converted in a $1 / 2 \mathrm{hr}$ run?

 


- In a homogeneous isothermal liquid polymerization $20 \%$ if the monomer disappears in $34 \mathrm{~min}$, For initial monomer concentration of 0.04 , also for $0.8 \mathrm{~mole} / \mathrm{lt}$, what is the rate of disappears of monomer?

 


- A liquid phase reaction $A+B \rightarrow P$ is carried out in a batch reactor. Initial concentration of $A$ \& $B$ are $1 \mathrm{kmol} / \mathrm{m}^{3} \& 1.2 \mathrm{kmol} / \mathrm{m}^{3}$. Fractional conversions of the limiting reactant are observed at different time as given in the table. Calculate the reaction velocity constant, if the reaction is of $1^{\text {st }}$ order with respect to both the reactants. \begin{tabular}{|l|l|l|l|l|l|l|l|l|l|} \hline$t(s)$ & 60 & 120 & 180 & 300 & 600 & 900 & 1800 & 2700 & 3000 \\ \hline$x_{A}$ & 0.14 & 0.26 & 0.35 & 0.48 & 0.66 & 0.76 & 0.89 & 0.94 & 0.95 \\ \hline \end{tabular}
