Answer to Question #8057 in Inorganic Chemistry for godzgirl

Question

for the reaction:2NO(g)+2H2(g)+<--->N2(g)+2H2O(g) at equilibrium in a 2.0L container at 25C. Suppose 3.00 moles of each component is put into the container. At equilibrium, 2.00 moles of NO is present. What is Kc for the reaction at this temperature? Do I set up an ICE chart? Please show me how you got this anwer. Thank you.
