The change in activation energy of a reaction without catalyst at 600 K and with catalyst is given. Also, the time of uncatalyzed reaction to occur is given. Based on these data, the time ofcatalyzed reaction is to be calculated. Concept introduction: The substance that speeds up the rate of reaction without getting consumed itself in a chemical reaction is known as catalyst. The relationship between the rate constant and temperature is given by the Arrhenius equation, k = A e − E a R T ln k = − E a R T + ln A To determine : The total time of catalyzed reaction.

Interpretation Introduction
Interpretation: The change in activation energy of a reaction without catalyst at
600K and with catalyst is given. Also, the time of uncatalyzed reaction to occur is given. Based on these data, the time ofcatalyzed reaction is to be calculated.
Concept introduction: The substance that speeds up the rate of reaction without getting consumed itself in a chemical reaction is known as catalyst.
The relationship between the rate constant and temperature is given by the Arrhenius equation,
k=Ae−EaRTlnk=−EaRT+lnA
To determine: The total time of catalyzed reaction.
For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check
the appropriate box.
Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below.
Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions
- just focus on the first stable product you expect to form in solution.

As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule
with a new C - C bond as its major product:
H₂N
O
H
1.
?
2. H3O+
If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more
than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for
example to distinguish between major products with different stereochemistry.
0
If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank.
