Answer is:<span>value of Keq for the reaction is </span>1,6·10⁻⁵.
Chemical reaction: 2NOCI(g) ⇄ 2NO(g) + CI₂<span>(g).
</span>[NOCl] = 1,4·10⁻²<span> M.
[NO] = 1,2</span>·10⁻³<span> M.
[Cl</span>₂] = 2,2·10⁻³<span> M.
</span>K = [NO]² · [Cl₂] ÷ [NOCl]².
K = (1,2·10⁻³ M)² · 2,2·10⁻³ M ÷ (1,4·10⁻² M)².
K = 1,6·10⁻⁵.
Double replacement means a reaction that includes two molecules that each have two different ions. After the reaction, the ions pairs have switched, which is what is shown in the above equation.
A single replacement would be a very simple reactions such as:
2Fe(II)S + Ov2^2- -> 2Fe(II)O + 2S^2-
A decomposition reaction would be shown as this:
2NaCl -(dissolve in water)> 2Na^+ + Clv2^-
A synthesis reaction could be the exact opposite:
2Na^1+ + Clv2^1- -> 2NaCl
