Problem #1
In the presence of a homogeneous catalyst of a given concentration aqueous reactant A converted to product at the following rates and CAo alone determined this rate.
CA mol/lit 1 2 4 6 7 9 12
-r mol/lit.hr 0.06 0.1 0.25 1.0 2.0 1.0 0.5
a) Find the time needed to lower the concentration of A from CAo= 10 mol/lit to CAf= 2mol/lit in a batch reactor.
b) What size of mixed flow reactor is needed for 60% conversion of a feed stream of 1000 mol/hr at CAo =8 mol/liter?

Problem 2:
The thermal decomposition of nitrous oxide (N2O)in the gas phase at 1030 K is studied in a constant volume batch reactor at different initial pressures of N2O The half- life data so obtained are as follows:
Po .mmHg 52.5 139 290 360
T1/2,sec 860 470 225 212
Determine a rate equation that fits these data

 The Batch reactor is the generic term for a type of vessel widely used in the process industries. Its name is something of a misnomer since vessels of this type are used for a variety of process operations such as solids dissolution, product mixing, chemical reactions, batch distillation, crystallization, liquid/liquid extraction and polymerization. In some cases, they are not referred to as reactors but have a name which reflects the role they perform (such as crystallizer, or bio reactor).

A typical batch reactor consists of a tank with an agitator and integral heating/cooling system. These vessels may vary in size from less than 1 litre to more than 15,000 litres. They are usually fabricated in steel, stainless steel, glass lined steel, glass or exotic alloy. Liquids and solids are usually charged via connections in the top cover of the reactor. Vapors and gases also discharge through connections in the top. Liquids are usually discharged out of the bottom.
