Question

What are some common mistakes students make with dynamic equilibrium?

Answer 1

I would say one common error is not emphasizing the fact that there are two processes (a forward and a reverse) which are both happening at the same time at equal rates.

The video below shows water which has salt added to the point where a saturated solution is created. Then more salt is added, a dynamic equilibrium will be established between the processes of dissolving and crystallization.

NaCl(s) `rightleftharpoons` NaCl(aq)
