Answer: The balanced equation for overall reaction is:
(CH3)3AuPH3 ----> C2H6 + (CH3)AuPH3
Explanation:
The reaction mechanism is given as follows:
Step 1: (CH3)3AuPH3 ↔ (CH3)3Au + PH3 (fast)
Step 2: (CH3)3Au → C2H6 + (CH3)Au (slow)
Step 3: (CH3)Au + PH3 → (CH3)AuPH3 (fast)
To balance this equation, firstly, we conduct proper atom count for each steps of the reaction mechanism.
It is important to note that for a reaction that involves several steps, the rate law is normally derived from the slow step ( which is step2 from the above mechanism).
Therefore, the balanced chemical equation for the overall reaction is:
(CH3)3AuPH3 ----> C2H6 + (CH3)AuPH3
The answer is C. Phospholipids because Lipids mean "Fat"
Answer: The energy of activation for the chirping process is 283.911 kJ/mol
Explanation:
According to the Arrhenius equation,
The expression used with catalyst and without catalyst is,
![\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]](https://tex.z-dn.net/?f=%5Clog%20%28%5Cfrac%7BK_2%7D%7BK_1%7D%29%3D%5Cfrac%7BEa%7D%7B2.303%5Ctimes%20R%7D%5B%5Cfrac%7B1%7D%7BT_1%7D-%5Cfrac%7B1%7D%7BT_2%7D%5D)
where,
= rate of reaction at 
= 194/min
= rate of reaction at 
= 47.6 /min
= activation energy
R = gas constant = 8.314 J/Kmol
tex]T_1[/tex] = initial temperature = 
tex]T_1[/tex] = final temperature = 
Now put all the given values in this formula, we get
![\frac{194}{47.6}=\frac{E_a}{2.303\times 8.314}[\frac{1}{278}-\frac{1}{301}]](https://tex.z-dn.net/?f=%5Cfrac%7B194%7D%7B47.6%7D%3D%5Cfrac%7BE_a%7D%7B2.303%5Ctimes%208.314%7D%5B%5Cfrac%7B1%7D%7B278%7D-%5Cfrac%7B1%7D%7B301%7D%5D)
Thus the energy of activation for the chirping process is 283.911 kJ/mol
