In chemical reaction, Conversion is an indication of (a) How much of the raw material reacted (b) How much of the raw material reacted into desired product (c) How much of the raw material reacted into undesired product (d) How much coke has formed Q43. Raising the temperature in the reactor will (a) Increase the rate of reaction (b) Decrease the rate of reaction (c) Not affect the rate of reaction (d) None of the above

Explanation / Answer

Question 40)

Regeneration is the process in which we re activate the catalyst so that it can be used again

Hence the answer is option b) The process of renewing a catalyst or making in reusable after it has accumulated reaction residue such as coke

question 41)

The picture shown is a typical diagram of a fluidized bed reactor where in the other column is used to regenerate the catalyst

Hence the answer is option d) Fluidized bed

Question 42)

The meaning of conversion of conversion implies to understand the how of the feed has reacted. However it does not give any idea regarding the feed getting converted into desired product. For desired product term "Selectivity" is popularly used.

Hence the answer is option a) How much of the raw material reacted

Question 43)

Increase the temperature of the reaction will increase the rate constant of the reaction which is a function of Temperature

Hence the answer is option a) increase the rate of reaction
