The heterogeneous reaction 2HCl (g) + I2 (s) -->(equilibrium)<--- 2HI(g) +Cl2(g) has Kc=1.6x10^-34 at 25 degrees C. Suppose 0.100 mol of HCl and solid I2 are placed in a 1.00L container. What will be the equilibrium concentration of HI and Cl2 in the container? The answer is: [HI] = 1.47x10^-12 M [Cl2] = 7.37x10^-13 M
