8) 4.00 mol HI are placed in an evacuated 5.00 L flask and then heated to 800 K. The system is allowed to reach equilibrium. Determine the equilibrium concentration of all species. What kind of problem do you think this is

Concentration of at equilibrium = 0.08 M

Concentration of at equilibrium =0.08 M

Concentration of = 0.64M

Explanation:

Moles of   = 4.00 mole

Volume of solution = 5.00 L

Initial concentration of =

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as

For the given chemical reaction:

Initial conc.      0.8 M           0 M    0 M

   At eqm. conc.  (0.8-2x) M   (x) M   (x) M    

The expression for is written as:

Concentration of at equilibrium = x M = 0.08 M

Concentration of at equilibrium = x M = 0.08 M

Concentration of = (0.8-2x) =

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
