Question 1

Equilibrium is established for the reaction  2X(s) + Y(g)2Z(g) at 500K,  Kc = 100. Determine the concentration of Z in equilibrium with 0.2 mol X and 0.50 M Y at 500K.
◦ 3.2 M
◦ 3.5 M
◦ 4.5 M
◦ 7.1 M
◦ None of these.

Question 2

For the equilibrium reaction 2SO2(g) + O2(g)2SO3(g), ΔHºrxn  = –198 kJ/mol.  Which one of these factors would cause the equilibrium constant to increase?
◦ Decrease the temperature.
◦ Add SO2 gas.
◦ Remove O2 gas.
