Question

Does the rate of reaction COMPLETELY STOP once chemical equilibrium has been reached....?

Answer 1

An old story....and the simple answer is NO!

Explanation:

Chemical equilibria define a KINETIC phenomenon...

[See here.](https://socratic.org/questions/what-characteristics-define-a-chemical-system-in-equilibrium)

And so `"chemical equilibrium"` does NOT specify CESSATION of chemical change; it does specify equality of FORWARD and REVERSE rates of chemical reaction....because chemical is manifestly occurring in both directions, reactants to products, and products to reactants, the scenario is `"dynamic"`. Good luck swallowing all that...
