Answer:
The activation energy is 164.02 kJ/mol
Explanation:
Log (k2/k1) = Ea/2.303R × [1/T1 - 1/T2]
k1 = 8.9×10^-4 s^-1
k2 = 9.83×10^-3 s^-1
R = 8.314 J/mol.K
T1 = 540 K
T2 = 578 K
Log (9.83×10^-3/8.9×10^-4) = Ea/2.303×8.314 × [1/540 - 1/578]
1.043 = 6.359×10^-6Ea
Ea = 1.043/6.359×10^-6 = 164020 J/mol = 164020/1000 = 164.02 kJ/mol
Answer:
Answer from thoughtco.com
The reason hydrogen bonding occurs is because the electron is not shared evenly between a hydrogen atom and a negatively charged atom. ... The result is that the hydrogen atom carries a weak positive charge, so it remains attracted to atoms that still carry a negative charge.

Starting on hydrogen going down the atomic radius goes up. And hydrogen to the right the atomic radius becomes smaller.
Answer:

Explanation:
The energy of transition of
is greater as compared to
as there are more quantum levels which leads to more energy.
Also, considering the expression as:
Where,
h is Plank's constant having value
c is the speed of light having value 
is the wavelength
Wavelength is inversely proportional to Energy. Thus, the transition which has lower energy corresponds to higher wavelength.
<u>Thus, answer -
</u>
