Bro you really expect us to read that for just 5 points and we all be to lazy to read that
Answer:
1. 67.2 kJ/mol
Explanation:
Using the derived expression from Arrhenius Equation

Given that:
time
= 8.3 days = (8.3 × 24 ) hours = 199.2 hours
time
= 10.6 hours
Temperature
= 0° C = (0+273 )K = 273 K
Temperature
= 30° C = (30+ 273) = 303 K
Rate = 8.314 J / mol
Since 
Then we can rewrite the above expression as:








Answer:
from the pic:

since molar mass is 118.084 g/mol;


It is an aldehyde with structure ( second pic )
The correct answer would be option 3. I order for a single displacement to occur there must be a single element and one compound. From then, the single element will then swap places with one of the elements in the compound (or in this case single circle and combined circles). Hope this helped!
