10. Suggest how two very different variables could be manipulated to increase the percent yield of sulphur trioxide. The equation for the reaction follows.

2 SO2(g) + O2(g)>>> 2 SO3(g) + energy

Ok, I really don't know this one. Can you please help? Thanks!

You need to increase the yield of SO3. That means making the equilibrium for the reaction shift to the right. How can you do that? We could increase the concentration of SO2, increase the concentration of O2, decrease the concentration of SO3 (by removing it as it is formed), cooling the reaction (removing the energy in the form of heat), or increasing the pressure of the reaction (since there are 3 mols of gas on the left and only two on the right). My instinct tells me that incrasing pressure is one of the two that should be listed plus any one of the others (they are more or less the same type). I hope this helps.

To increase the percent yield of sulfur trioxide (SO3) in the given reaction, you can manipulate two variables: the concentration of SO2 and the concentration of O2.

1. Increase the concentration of SO2: By adding more SO2 to the system, you are increasing the number of reactant molecules available for the reaction. According to Le Chatelier's principle, if you increase the concentration of reactants, the equilibrium will shift in the direction that consumes those reactants. In this case, an increase in SO2 concentration would shift the equilibrium to the right, favoring the formation of more SO3.

2. Increase the concentration of O2: Similarly, if you increase the concentration of O2, you provide more reactant molecules for the reaction. This would also shift the equilibrium towards the product side, increasing the yield of SO3.

It's important to note that factors such as temperature, pressure, and the presence of a catalyst can also affect the percent yield of the reaction. However, in this specific equation, those variables do not directly influence the equilibrium position or yield of SO3.

Remember to always consult reliable reference materials or seek expert advice for specific reaction conditions and optimizations.
