Hydrogen gas, iodine vapor and hydrogen iodide gas are added to an evacuated flask until the concentrations of H2 and I2 are both 2.0 M and that of HI equals 8.0M K=9.00 at 423C

The reaction vessel is heated to 675 where the equilibrium concentration of the HI is determined to be 6.0M What is the K value at 675C

Answer #1

Solution-
The reaction is written as

H2(g) + I2(g) <==> 2HI(g) --- Kc = 9.0

2M .......2M ............ 8M

Kc = [HI]^2 / [H2] [I2]

Q = (8)^2/ / (2)^2)

Q = 64 / 4

Q = 16

b)- Reaction H2cvt I 2 - 241 dorint -2. . Colpa E (3 (d) (r) 3 do 6 bK = 6 03) (3) = 4

    Hydrogen iodide, HI, is formed in an equilibrium reaction when gaseous hydrogen and gaseous iodine gas are heated together. First, write the equilibrium reaction and balance it. The volume of the reactor is not changing during the process. Now, if 24.2 g of H2 and 24.2 g of I2 are heated, they form 9.9 g of hydrogen iodide, what mass of hydrogen remains unreacted? No unit is needed. At least 3 sig fig is needed. Avoid too much rounding! You...
