1. Answer the following: A. Write an equilibrium expression for the dissociation of acetic acid. B. Write an equilibrium expression for the dissociation of HCl. C. Which K is larger? Part C is my biggest problem. Numbers weren't given to work with. So how would I even approach this?
Homework Answers
(C)
For HCl , the value of K is larger. Because it is strong acid than
acetic acid. Hence its degree of dissociation is very higher than
acetic acid.as degree of dissociation more , more product wil form
and less reactant remains .
So ratio of products to reactant is higher.
