For the gaseous reaction 2A B, where the feed consists of 50 mole % A and 50 mole % inerts, the expansion factor is

The molecularity and the order of reaction respectively, for the hydrolysis of methyl acetate in presence of acids are

The irreversible reaction is a special case of reversible reaction, if the

A pollutant P degrades according to first order kinetics. An aqueous stream containing P at 2 kmole/m³ and volumetric flow rate 1m³ /h requires a mixed flow reactor of volume V to bring down the pollutant level to 0.5 kmole/m³ . The inlet concentration of the pollutant is now doubled and the volumetric flow rate is tripled. If the pollutant level is to be brought down to the same level of 0.5 kmole/m³ , the volume of the mixed flow reactor should be increased by a factor of

For the liquid phase parallel reactions:
R, r_R = K₁.C_A2; E₁ = 80 KJ/mole
S, r_s = K1.C_A ; E₂ = 120 KJ/mole
The desired product is R. A higher selectivity of R will be achieved, if the reaction is conducted at
