Question 1

Phosgene, COCl2, a poisonous gas, decomposes according to the equation COCl2(g) CO(g) + Cl2(g).  Calculate Kp for this reaction if Kc = 0.083 at 900ºC.
◦ 0.125
◦ 8.0
◦ 6.1
◦ 0.16
◦ 0.083

Question 2

Sodium carbonate, Na2CO3(s), can be prepared by heating sodium bicarbonate, NaHCO3(s) as shown below.

         2NaHCO3(s) Na2CO3(s) + CO2(g) + H2O(g)      Kp = 0.23 at 100ºC

If a sample of NaHCO3 is placed in an evacuated flask and allowed to achieve equilibrium at 100ºC, what will the total gas pressure be?
◦ 0.46 atm
◦ 0.96 atm
◦ 0.23 atm
◦ 0.48 atm
◦ 0.11 atm
