Answer: The at equilibrium is 0.561 M.
Explanation:
The given data is as follows.
Volume of flask = 0.32 L,
No. of moles of = 0.041 mol,
No, of moles of CO = 0.26 mol, No. of moles of = 0.091 mol
Equilibrium constant, K = 0.26
Balanced chemical equation for this reaction is as follows.
Hence,
K = ...... (1)
First, we will calculate the molarity or concentration of given species as follows.
= 0.128 M,
= 0.8125 M,
= 0.284 M
Therefore, using expression (1) we will calculate the as follows.
K =
or,
=
=
= 0.561 M
Thus, we can conclude that the at equilibrium is 0.561 M.
