The equilibrium constant, Kc, for the following reaction is 1.47×10-2 at 628 K. 2HI(g) H2(g) + I2(g)

When a sufficiently large sample of HI(g) is introduced into an evacuated vessel at 628 K, the equilibrium concentration of I2(g) is found to be 0.323 M.

Calculate the concentration of HI in the equilibrium mixture. M

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
