Problem
At 700 K the following reaction is at equilibrium:
H
2
(
g
)
+
I
2
(
g
)
⇌
2
HI
(
g
)
.
\text{H}_2(g)+\text{I}_2(g)\rightleftharpoons 2\,\text{HI}(g).
H
2
(
g
)
+
I
2
(
g
)
⇌
2
HI
(
g
)
.
The equilibrium concentrations are
[
H

]
=
0.15
M
[\text{H}_2]=0.15\,\text{M}
[
H
2
]
=
0.15
M
,
[
I

]
=
0.15
M
[\text{I}_2]=0.15\,\text{M}
[
I
2
]
=
0.15
M
, and
[
HI
]
=
0.70
M
[\text{HI}]=0.70\,\text{M}
