Step-by-Step Solution:

Solution 62P :

Step 1:

Given the reaction:

H2(g) + I2(g) ⇋ 2HI(g)

Here, we have to complete the table assuming that all concentrations are equilibrium concentrations in moles per liter, M.

T(°C)

H2

[I2]

[HI]

Keq

0.0468

______

50.2

We know the formula for equilibrium constant (Kc or Keq):

                Keq =  , i.e  Keq =

Now, consider 1st row :

T(°C) = 25

H2 = 0.355

[I2] = 0.388

[HI] = 0.0922

Keq = ?

Hence, Keq =

              = 0.0617

Step 2:

Now, consider 2nd row :

T(°C) = 340

H2 = ?

[I2] = 0.0455

[HI] = 0.387

Keq = 9.6

         Keq =

        9.6 =

        [] =

                  = 0.34287
