Quiz 3 Prep Fall 2014

Postby emilyharland » Tue Nov 15, 2016 4:15 pm

On question number 6, it asks what conditions favor SO2(g) production in the equation 2SO3(g) <-> 2SO2(g) + O2(g). I understand how increasing the temperature would favor the products but the other condition is low pressure. Wouldn't lowering the pressure cause the molecule to shift towards the reactants and therefore not favor SO2 production? If anyone could clear this up that would be great.

Lowering the pressure (by way of increasing volume) will favor the side with more moles of gas. In this reaction there are 3 moles of gas on the right and 2 on the left, so lower pressure will increase SO2 production.
