Answer: Equilibrium concentration of at
is 4.538 M
Explanation:
Initial concentration of = 0.056 M
Initial concentration of = 4.60 M
The given balanced equilibrium reaction is,
Initial conc. 0.056 M 4.60 M 0 M 0 M
At eqm. conc. (0.056-x) M (4.60-2x) M (x) M (6x) M
The expression for equilibrium constant for this reaction will be,
Given : equilibrium concentration of =x = 0.031 M
Concentration of = (4.60-2x) M =
=4.538 M
Thus equilibrium concentration of at
is 4.538 M
