$3\mathrm{.}2$ Liquid a sedomposes by first$-$order kinetics, and in a batch reactor $50\%$ of $A$ is converted in a $5-$minute run. How much longer would it take to reach $75\%$ conversion?

$3\mathrm{.}4$ A $10-$minute experimental run shows that $75\%$ of liquid reactant is converted to product by a $\frac{1}{2}-$order rate. What would be the fraction converted in a half$-$hour run?

$3\mathrm{.}6$ After $8$ minutes in a batch reactor, reactant $)=(1\frac{\text{m}\text{o}\text{l}}{l}$iter is $80\%$ converted; after $18$ minutes, conversion is $90\%.$ Find a rate equation to represent this reaction.

$3\mathrm{.}10$ Aqueous A reacts to form $R(AR)$ and in the first minute in a batch reactor its concentration drops from $C_{A0}=2\mathrm{.}03mo\frac{l}{l}$iter to $C_{Af}=1\mathrm{.}97mo\frac{l}{l}$iter. Find the rate equation from the reaction if the kinetics are second$-$order with respect to $A.$
