The price would not be a physical property
Answer:
The value of equilibrium constant is 29.45.
Explanation:
Moles of hydrogen gas = 2.00 mol
Concentration of hydrogen gas =
Moles of iodine gas = 1.00 mol
Concentration of iodine gas =
initially
2.00 M 1.00 M 1.00 M
At equilibrium:
(2.00-x/2) (1.00-x/2) x
Moles of HI at equilibrium = 1.80 M
Concentration of HI at equilibrium =
The expression of an equilibrium constant is given by ;
Putting x equal to 1.80 M.
The value of equilibrium constant is 29.45.
I believe that the delta h formation or enthalpy of
formation is only zero for pure elements. They are zero because they are the
most basic substances, that is you cannot form an element from an element.
Since Ozone is already a compound, a mixture of 2 oxygen O2 atoms, therefore
the δh∘<span>f is
not necessarily zero.</span>
