(Exp R) For the half reaction:
Al
3+
(aq)
+ 3 e
-
Al
(s)
the Nernst equation would predict the slope of the graph that has E
half-cell
plotted on the
y-axis and log
1
[Al
3+
]
along the x-axis to be:
a.
-8.56x10
-3
b.
-0.0197
c.
-0.0296
d.
-0.0592
e.
-0.178

(Exp S) The rate equation for the reaction:
2 Fe
3+
(aq)
+ 2 I
-
(aq)
2 Fe
2+
(aq)
+ I
2(aq)
was found to be:
[I2]
t
= k [Fe
3+
] [I
-
]²
If the concentration of I
-
is doubled while the concentration of Fe
3+
remains constant, the
observed reaction rate would
a.
be quadruple the original rate
b.
be double the original rate
c.
remain the same
d.
decrease to one half the original rate
e.
decrease to one quarter the original rate
