Answer : The temperature for non-catalyzed reaction needed will be 456 K
Explanation :
Activation energy : The energy required to initiate the reaction is known as activation energy.
According to the Arrhenius equation,

Since, the rate for both the reaction are equal.


..........(1)
where,
= activation energy for non-catalyzed reaction = 75 kJ/mol
= activation energy for catalyzed reaction = 49 kJ/mol
= temperature for non-catalyzed reaction = ?
= temperature for catalyzed reaction = 
Now put all the given values in the above formula 1, we get:



Therefore, the temperature for non-catalyzed reaction needed will be 456 K
I’m pretty sure it’s 30.06904
Explanation:
Relation between pressure of water and its droplet is as follows.
where, p = pressure of droplet
= water pressure in given temperature
=
M = Molecular Weight in Kg/Mol (0.018 for water)
r = radius in meters
= density of water in
(1000
)
R = ideal gas constant (8.31)
T = temperature in Kelvin
(a)
We will calculate the value of p as follows.
p =
=
= 26.8 torr
(b) And, vapor pressure of spherical water droplets of radius 2.0
or 
p =
=
= 25.2 torr
<span>Zn⁰(s) + CuSO4(aq) --> Zn²⁺SO4²⁻(aq) + Cu(s)
</span>Zn⁰ --- in free elements oxidation number is 0.
Zn²⁺SO4²⁻ ---- ionic compound , it has ion Zn²⁺, so oxidation number here is +2.
<span>The oxidation number of Zn changes from 0 to +2.</span>
You can use a fan on the wire. That's one way.
