CHEM 112 Chapter 13 (z8) 1) Consider the following reaction 2 (g) 02 (g) 2 NO If the equilibrium partial pressures of N2, o, and No are o.15 atm, o.33 atm and 0.050 atm respectively at 2200 C What is Kp? (4 pts) 2) Write the equilibrium expression for 2 NH3 3 H2 N2 3) The equilibrium constant for the formation of N2H4 is Ke 5.00 x 10 N2+ 2 H2 N2H4 All species are gases. Suppose 2.00 mol of H2 and 1 mol ofN2 are placed in a 1.00 L container. Calculate the equilibrium concentrations of all species at equilibrium (5 pts)Explanation / Answer
Answer(1)
N2(g) + O2(g) ---> 2 NO(g)
Kp = p(NO)^2/p(N2)*p(O2)
Kp= (0.050^2)/((0.15)*(0.33))
Kp = 0.051
Answer(2)
For the ammonia system, the equilibrium expression is:
Keq = [NH3]^2 / [H2]^3[N2]
