The equation for the reaction is

2S(g) + 3O2(g) ---> 2SO3(g)

Consider a mixture of sulfur atoms and dioxygen molecules in a closed container below:

For each of the following explain why the representation is correct or incorrect. (Click on a diagram for an answer.)

In this diagram the container has the correct product, SO3. But the problem is there is not enough product. The original diagram above shows 6 molecules of dioxygen, and six atoms of sulfur. This digram shows only two molecules of SO3. There is more product than is indicated here.
