Question

The dynamic part of chemical equilibrium refers to _____________.
Select one:
a. the fact that it is very interesting to observe
b. the changes taking place, even though equilibrium has been reached
c. the one way molecular change of the forward reaction
d. the visible changes occurring as the forward and reverse reaction take place

Answer 1

I'll say B is the correct answer. One key concept to chemical equilibrium is that the concentration of the products in relative to the reactants (or reagents) does not change. The reaction is still going on, but there's no NET change.

so a would be wrong because any observable characteristics would hint a change in the composition, so no, not in equilibrium. As for d, at equilibrium, even though there's still reaction, there's no visible changes. And c just doesn't make sense to me ( I'll be happy if anybody can explain to me what it means).

So, in short, B
