Question 1

A reaction with an equilibrium constant K_c = 1.5 x 10²¹ would consist of which of the following at equilibrium:
◦ approximately equal reactants and products
◦ some reactants and products with reactants slightly favored
◦ some reactants and products with products slightly favored
◦ essentially all reactants
◦ essentially all products

Question 2

At 250ºC, the equilibrium constant K_p for the reaction PCl₅(g)

PCl₃(g) + Cl₂(g) is 1.80. Sufficient PCl₅ is put into a reaction vessel to give an initial pressure of 2.74 atm at 250ºC. Calculate the pressure of PCl₅ after the system has reached equilibrium.
◦ 1.50 atm
◦ 1.24 atm
◦ 4.24 atm
◦ 0.94 atm
◦ 1.12 atm
