Problem 62P

Consider the reaction: Complete the table. Assume that all concentrations are equilibrium concentrations in moles per liter, M.

 T(°C) H2 [I2] [HI] Keq 25 0.355 0.388 0.0922 ______ 340 ______ 0.0455 0.387 9.6 445 0.0485 0.0468 ______ 50.2
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 25 0.355 0.388 0.0922 ______ 340 ______ 0.0455 0.387 9.6 445 0.0485 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
