Use the following image to answer the following questions. A student was performing an experiment using two identical cups made
of styrofoam. The student had Cup A holding water at 90℃ and Cup B holding water at 20℃. The student then put an Aluminum Bar into each cup that was touching the water. As time passed, the student noticed that the temperature of the water in Cup A and Cup B began to change. Question:
A. Predict what will happen to the temperature of the water in Cup A and Cup B after 1 hour has passed.
B. Explain and give evidence for what type of heat transfer is occurring between the 2 cups.

Answer:
Explanation:
Hello,
In this case, by using the Henderson-Hasselbach equation one can compute the concentration of acetate, which acts as the base, as shown below:
Regards.
Answer:
Part a: <em>Units of k is </em><em> where reaction is first order in A and second order in B</em>
Part b: <em>Units of k is </em><em> where reaction is first order in A and second order overall.</em>
Part c: <em>Units of k is </em><em> where reaction is independent of the concentration of A and second order overall.</em>
Part d: <em>Units of k is </em><em> where reaction reaction is second order in both A and B.</em>
Explanation:
As the reaction is given as
where as the rate is given as
where x is the order wrt A and y is the order wrt B.
Part a:
x=1 and y=2 now the reaction rate equation is given as
Now the units are given as
The units of k is
Part b:
x=1 and o=2
x+y=o
1+y=2
y=2-1
y=1
Now the reaction rate equation is given as
Now the units are given as
The units of k is
Part c:
x=0 and o=2
x+y=o
0+y=2
y=2
y=2
Now the reaction rate equation is given as
Now the units are given as
The units of k is
Part d:
x=2 and y=2
Now the reaction rate equation is given as
Now the units are given as
The units of k is
