Calculating Fractional Coverage

If K_CO=1 atm^-1 amd K_NO=5 atm^-1, what is the ratio of sites containing CO to those containing NO when the conversion is 20%? 99%? What fraction of sites are occupied by NO? by CO? The feed is equal molar in CO and NO with P_O=2 atm.

If K_CO=1 atm^-1 amd K_NO=5 atm^-1, what is the ratio of sites containing CO to those containing NO when the conversion is 20%? 99%? What fraction of sites are occupied by NO? by CO? The feed is equal molar in CO and NO with P_O=2 atm.

Solution

Fraction of CO sites.

For X=.2

at 20% conversion 15% of the sites are occupied by CO and 9.4% are vacant.

For X=.99

at 99% conversion 1.8% of the sites are occupied by CO and 89% are vacant.
