Answer:
for the given reaction is -99.4 J/K
Explanation:
Balanced reaction:
where represents standard entropy.
Plug in all the standard entropy values from available literature in the above equation:
So, for the given reaction is -99.4 J/K
Answer:
The pH of the solution will be 7.53.
Explanation:
Dissociation constant of KClO=
Concentration of acid in 1 l= 0.30 M
Then in 200 ml =
The concentration of acid, HClO=[acid]= 0.006 M
Concentration of salt in 1 L = 0.20 M
Then in 300 ml =
The concentration of acid, KClO=[salt]= 0.006 M
The pH of the solution will be given by formula :
The pH of the solution will be 7.53.
