Question

why the quantum for the hydrogen chlorin reaction is very high?​

Answer 1

Answer:

A striking feature of the photochemical reaction between hydrogen and chlorine is the extremely large quantum yield that is obtained,

In the photosynthesis of HCl, the first step of the secondary process which immediately follows the primary process is exothermic and hence takes place easily, and consequently, chain reaction start and the quantum yield is very high.

Answer 2

• As we know that hydrogen chlorine is produced before terminating the reaction.

• Due to the chain propagating reaction in a secondary process the quantum for the hydrogen chlorine reaction is very high.

• The first step of the secondary process is exothermic.

• The first step immediately follows the primary process.

• So that it takes place easily, and quantum yield is very high.
