A mixture of 5.00×10^-3 mole of H2 and 5.00×10^-3 mole of I2 are placed in a 5.0L container at 350° C and allowed to come to equilibrium. At equilibrium the concentration of HI is 5.00×10^-4 M.

a) What is the Kc at 350°C for the reaction H2 (g) + I2(g) --> 2HI (g)?

b) What is the equilibrium of H2 (g)?

At 25°C Kc = 4.5 for the reaction
SO3(g) + NO(g) --> NO2(g)+ SO2(g)
If 0.50 mole of SO3 and 0.50 mole of NO are placed in a 5.0L container and are allowed to react.

a) what will be the equilibrium concentration of SO2(g)?

b) what will be the equilibrium concentration of SO3(g)?

c) what is the Kp at 25° C?
