Practically every hydrogenation reaction cannot be reversed by increasing temperature.(a) True(b) FalseI got this question by my college professor while I was bunking the class.Query is from Kinetic and Thermodynamics of Hydrogenation Reaction topic in section Hydrogenation of Unit Processes

Answer»

The correct answer is (b) False

Explanation: Temperature is one of the most important VARIABLES affecting a reaction. Practically every hydrogenation reaction can be reversed by increasing temperature. It becomes necessary, then, to work at as IOWA temperature as POSSIBLE where the rate of reaction will still be satisfactory. Whereas catalysts affect only the speed and COURSE of a reaction, temperature AFFECTS the equilibrium position, the speed, and the path, or course, of a reaction.
