Question

Apply Lechatelier’s principle in getting the maximum yield of sulphur trioxide and their effect on the economics of the process.

Answer 1

Answer:

I dint understand anything

Answer 2

Explanation:

the proportion of sulphur dioxide to oxygen in the reaction mixture:

Equilibrium: The oxygen in the air is cheap, while the sulphur dioxide is more expensive and also a  pollutant. It is therefore important to convert as much of it as possible into sulphur trioxide.

According to Le Chatelier, increasing the concentration of something on the left-hand side of the

equilibrium will shift the equilibrium to the right. Therefore it makes sense to increase the amount

of oxygen above equation proportions.

Rates: There aren't any important rate considerations here.

Economics: You can't increase the proportion of oxygen too much, because that would clutter up

the reactor with molecules that have nothing to react with. You could end up with a better

percentage conversion, but a smaller total amount of sulphur trioxide formed in a given time. The

1 : 1 ratio is the best compromise.
