Question 1:
Consider the following reaction:?
2 HCl(g) <--> H2(g) + Cl2(g) Kc = 0.347
Initially the concentration of all species in the flask were 1.0 mol/L. What is the concentration of the HCl(g) at equilibrium?
A-1.32
B-1.26
C-1.37
D-1.54
Question 2:
2 NH3(g) <--> N2(g) + 3 H2(g) Kc=0.784
Initially only ammonia gas is placed in a flask. After equilibrium has been reached it is found that the concentration of the nitrogen gas in the flask is 0.500mol/L. What is the initial concentration of the ammonia gas? (answer to 3 Significant digits)
