What is the Y value in the concentration of the SCN⁻
Suppose the Keq for this experiment is 523.
The initial concentration of the Fe³⁺ is 4.00 x 10⁻² M
The initial concentration of the SCN is 1.00 10⁻³ M
The reaction of the experiment: Fe³⁺ + SCN ⇋ Fe(NCS)²⁺
The concentration of the SCN at equilibrium is : Y x 10⁻⁴ M
Your answer should have 2 sf ___
