Question

The temperature and pressure required for reforming benzene from n-hexane is

• A. 473 K, 10-20 atm
• B. 773 K, 10-20 atm
• C. 523 K, 100 atm
• D. 973 K, 1-2 atm
• E. 573 K, 10-20 atm

Hint:

For catalytic reforming of n-hexane to produce benzene, 523 K and 100 atm is the optimal temperature and pressure range for efficient conversion.

Answer 1

The Correct Option is C

The process of reforming benzene from n-hexane involves catalytic reforming, which is a chemical process that uses heat and pressure to convert straight-chain alkanes, such as n-hexane, into aromatic hydrocarbons like benzene. The key conditions for this reaction include specific temperatures and pressures. - Option (A): 473 K, 10-20 atm are not ideal conditions for this process. These conditions are generally used for other types of catalytic reactions but not for the reforming of benzene. - Option (B): 773 K, 10-20 atm is too high a temperature for the process, and it may lead to the degradation of the desired product. - Option (C): 523 K, 100 atm is the correct answer. Reforming of n-hexane to benzene typically occurs at a temperature of 523 K (high temperature) and a pressure of 100 atm. These conditions are optimal for producing the aromatic hydrocarbons. - Option (D): 973 K, 1-2 atm is too high a temperature and too low a pressure for the reforming process, leading to inefficient conversion. - Option (E): 573 K, 10-20 atm are conditions that are not typically used for benzene reforming. Thus, the correct answer is (C) 523 K, 100 atm.
