problem 5I.11

[Athena L 1B]

Can someone explain how to do number 11? I'm not sure if I'm just making calculation errors or if I am doing the problem fundamentally wrong but I can't seem to get the right answer.

Please post the question!

A reaction vessel of volume 0.500 L at 700. K contains 1.20 mmol SO2(g), 0.50 mmol O2(g), and 0.10 mmol SO3(g). At 700. K, Kc = 1.7 x 10^6 for the equilibrium 2SO2(g) + O2(g) <=> 2SO3(g). a) Calculate the reaction quotient b) will more SO3(g) tend to form?

Part (a) is asking to calculate Q. Convert mmol to mol and divide by volume. These are your concentrations. plug it into the formula [P]/[R] making sure to use correct stoichiometric coefficients. This is Q. Part (b) compare the Q to the given K. if Q<K, reaction shifts right. Q>K, reaction shifts left. Hope this helps. I did this on the toilet
