Threshold energy in a reaction is equal to the_________________?
Correct answer: C. Sum of A. & B.
- A. Activation energy
- B. Normal energy of reactants
- C. Sum of A. & B.
- D. Neither A. nor B.
Explanation
Threshold energy is the minimum energy required for reactants to reach the activated state, so it equals the normal reactant energy plus the activation energy. Therefore, option c is the appropriate relation.

In Langmuir treatment of adsorption,_________________?
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 k.mole/m3, the volume of the mixed flow reactor should be increased by a factor of_______________?
