At equilibrium we have 9 moles of
Explanation:
Always start with the balanced chemical equation. In the gas phase, hydrogen and iodine will produce hydrogen iodide
This tells us the proportions in which the reactants react.
If we have 10 moles of
From the equation, one mole of hydrogen gas reacts with one mole of iodine gas. Therefore, only one mole of iodine reacts and we are left with
For every mole of hydrogen gas that reacts, two moles of HI are formed. If we started with none, one mole of hydrogen dissociating will result in two moles of HI forming.
