Solving when both products are present initially

Solving an equilibrium problem when both
products are present initially

Before you answer the following questions it may be helpful to read the section in your text book about "Q" the reaction quotient.

If you check the main screen you'll see that when the applet solved the problem to get the number of moles of each substance at equilibrium it came up with a value of "x" that is a negative number! What does it mean when you get a negative "x" value?

	Equilibrium was not really reached.
	Equilibrium was reached when N2 and H2 molecules combined to form more NH3 molecules. That is, the equilibrium N2 + 3H2 2NH3 shifted right.
	Equilibrium was reached when NH3 molecules decomposed into N2 and H2 molecules. That is, the equilibrium N2 + 3H2 2NH3 shifted left.
	I have no clue! I need a hint!
