Question 7

An industrial batch reactor is closed while this reversible reaction takes place:

J⇌K \text{J} \rightleftharpoons \text{K} J⇌K

The reaction mixture reaches equilibrium. The measured amount of J then remains constant.

A technician concludes that particles of J are no longer changing into particles of K.

Explain why the technician's conclusion is incorrect.
