Question

Thermodynamically dehydrogenation reactions are favorable at ___________

(a) High temperature, low pressure

(b) Low temperature, high pressure

(c) High temperature, high pressure

(d) Low temperature, low pressure

I got this question in a national level competition.

This interesting question is from Natural Products in chapter Natural Products of Chemical Technology

Answer 1

Correct answer is (a) High temperature, low pressure

The best explanation: Thermodynamically dehydrogenation reactions are favorable at High temperature and low pressure. Hydro cracking and carbon deposition can occur at high temperature, hence high hydrogen pressures are used to reduce them.
