1. The reaction I2(g) + Cl2(g) ⇔ 2 ICl(g) is at equilibrium when the partial pressures are: I2 = 0.027 atm, Cl2 = 0.027 atm and ICl = 0.246 atm. The partial pressure of ICl is then increased to 0.500 atm by adding ICl.

a. When the system re-establishes equilibrium, what is the partial pressure of Cl2(g)?

b. When the system re-establishes equilibrium, what is the partial pressure of ICl(g)

c. When the system re-establishes equilibrium, what is the partial pressure of I2(g)

2. 2 NaHCO3(s) ⇔ Na2CO3(s) + H2O(g) + CO2(g)   enthalpy = +128 kJ is at equilibrium.  

a. What happens to [Na2CO3(s)] when NaHCO3 is added?

b. What happens to Kc when the temperature increases?

c. What happens to [CO2] when the H2O is added?

d. What happens to the value of Kp when Na2CO3 is added?
