It makes salt and water :)
The straight horizontal line shows us that the object is moving at a constant speed
Answer:
Value of for the given reaction is 7.7
Explanation:
Where represents solubility product
For the given reaction, (concentration of pure solids remain constant during reaction. Hence their concentration is taken as 1 to exclude them from equilibrium constant expression)
So,
or,
Hence option (B) is correct
The question is incomplete , complete question is ;
A student prepares a 0.30 mM aqueous solution of acetic acid . Calculate the fraction of acetic acid that is in the dissociated form in his solution. Express your answer as a percentage. The
Answer:
21.43% is the percentage of acetic acid that is in the dissociated form in its solution.
Explanation:
The value of acetic acid = 4.756
The dissociation constant of acetic acid =
The initial concentration of acetic acid = c = 0.30 mM =
Degree of dissociation of acetic acid =
initially
c 0 0
At equilibrium
(c-cα) cα cα
The expression of dissocation constant :
21.43% is the percentage of acetic acid that is in the dissociated form in its solution.
