Definition of "equilibrium pos

Equilibriumposition means the concentrations of all components in an equilibrium state.

For example, consider the reaction H2(g) + I2(g) ⇌ 2HI(g)
In a certain equilibrium state at 500 K :
[H2] = [I2] = 0.1 mol dm⁻³and [HI] = 0.4 mol dm⁻³
The equilibrium position of the above equilibrium state is that "theconcentrations of H2, I2 and HI are 0.1, 0.1 and 0.4 moldm⁻³ respectively."
