Hydrogen gas is mixed with a nitrogen ‘bath gas’. The overall pressure is p^{\ominus}. If the mole fraction of the hydrogen is expressed as 10 per cent, what is its activity?
Step-by-Step
By definition, x_{({X})}=\mathrm{partial~pressure},\,p_{({X})}, so
a_{(\mathrm{H}_{2})}=p_{(\mathrm{H}_{2})}\div p_{(\mathrm{total})}=0.1
