what is the value of the acid dissociation constant for a weak acid?
how come the answer is less than one (1)?

Weak acids don't ionize 100%. In fact, that is the definition of a weak acid; i.e., strong acids ionize 100% while weak acids ionize less than 100%. If any acid ionizes less than 100% then the dissociation constant must be less than one because the numerator numbers will be less than the denominator numbers.
