<u>Answer:</u> The equilibrium concentration of HCl is
<u>Explanation:</u>
We are given:
Moles of = 0.564 moles
Volume of vessel = 1.00 L
Molarity is calculated by using the equation:
Molarity of
The given chemical equation follows:
<u>Initial:</u> 0.564
<u>At eqllm:</u> 0.564-x x x
The expression of for above equation follows:
The concentration of pure solid and pure liquid is taken as 1.
We are given:
Putting values in above equation, we get:
Negative sign is neglected because concentration cannot be negative.
So,
Hence, the equilibrium concentration of HCl is
