question 9 & 10

Two gases are added to a 1.00L container: 2.0 moles of A;4.0 moles of B. These gases react as follows: A(g)+3B(g)C(g)+2D(g) At equilibrium the container contains 0.6 moles of D. Calculate the concentration of B at equilibrium. Include the appropriate unit and answer to 2 significant figures. Answer: If Kc=0.68 for this reaction 3H2(g)+N2(g)2NH3(g) what is the value for Kc for the following reaction at the same temperature? g question 6NH3(g)9H2(g)+3N2(g) Answer to 2 significant figures
