space space space space space space space space space space space space space space space space space NH subscript 2 COONH subscript 4 space space space rightwards arrow space space 2 NH subscript 3 space space plus space space space CO subscript 2

space At space straight t equals 0 space space space space space space space space space straight a space space space space space space space space space space space space space space space space space space space space space space space space space space space 0 space space space space space space space space space space space space space 0

space space At equals 0 space space space space space space straight a left parenthesis 1 minus straight k right parenthesis space space space space space space space space space space space space space space space space space space space 2 ak space space space space space space space space space space space ak

straight k space equals degree space of space dissociation
straight a space equals space initial space concentration

vant space hoff space factor space is space given space by space

straight i equals fraction numerator Total space conc. space at space time space straight t over denominator Initial space conc. end fraction

straight i equals space fraction numerator open square brackets space space straight a left parenthesis 1 minus straight k right parenthesis space plus space space 2 ak space plus space space ak close square brackets over denominator open square brackets straight a close square brackets end fraction

straight i equals space fraction numerator left square bracket straight a minus ak space plus space 2 ak space plus ak over denominator straight a end fraction

straight i equals space fraction numerator up diagonal strike straight a open parentheses 1 plus space 2 straight k close parentheses over denominator up diagonal strike straight a end fraction

straight i equals space 1 plus 2 straight k

For space stron space electrolytes space

straight i space equals space sum space of space no. space of space ions space in space the space product

Total space no. space of space ions space in space the space product space equals 2 plus 1
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 3

straight i space equals space 3

space 1 plus 2 straight k equals space 3

space space space space space space 2 straight k equals space 2

space space space space space space space space space straight k equals 1 space

therefore Degree space of space dissociation space of space ammonium space carbamate space is space 1.
