Speed/ velocity/ how fast the car is moving!
Hope this assists you!
Answer:
C. outside 45 degrees
Step-by-step explanation:
C. outside 45 degrees
because it can be any point or direction outside 45 degrees
The answer is A, the graph would have a horizontal shape. The answer is A.
Explanation:
The given data is as follows.
= (4 + 273) K = 277 K
= (22 + 273) K = 295 K
= 21.2
Formula to calculate activation energy will be as follows.
![ln \frac{k_{2}}{k_{1}} = \frac{E_{a}}{R} [\frac{1}{T_{1}} - \frac{1}{T_{2}}]](https://tex.z-dn.net/?f=ln%20%5Cfrac%7Bk_%7B2%7D%7D%7Bk_%7B1%7D%7D%20%3D%20%5Cfrac%7BE_%7Ba%7D%7D%7BR%7D%20%5B%5Cfrac%7B1%7D%7BT_%7B1%7D%7D%20-%20%5Cfrac%7B1%7D%7BT_%7B2%7D%7D%5D)
![ln (21.2) = \frac{E_{a}}{8.314 J/mol K} [\frac{1}{277} - \frac{1}{295}]](https://tex.z-dn.net/?f=ln%20%2821.2%29%20%3D%20%5Cfrac%7BE_%7Ba%7D%7D%7B8.314%20J%2Fmol%20K%7D%20%5B%5Cfrac%7B1%7D%7B277%7D%20-%20%5Cfrac%7B1%7D%7B295%7D%5D)
3.05 = 
= 115116.914 J/mol
or = 115.116 kJ/mol
Thus, we can conclude that overall activation energy (kJ/mol) of the process is 115.116 kJ/mol.
