Question
Hydrogen iodide gas was placed in an empty flask
at 145°C. The following equilibrium was
established.
2 HI(g) 2 H2(g) + I2(g)
At 145°C, the equilibrium constant for this
reaction is 0.167. If the initial concentration of
hydrogen iodide was 0.203 mol/L, what is the
equilibrium molar concentration of hydrogen iodide
gas?
Answer to three decimal places.
