The correct statements which are true for the reactions in the Sun are that are fusion reactions and reactions occur because of very high temperatures.
<h3>What is nuclear fusion?</h3>
Nuclear fusion reactions are those reactions in which two species reacts with each other for the formation of new specie.
In the core of the sun, nuclear fusion of hydrogen atoms occur for the formation of helium molecules in the presence of high temperature.
Hence, the correct statements are they are fusion reactions and reactions occur because of very high temperatures.

Answer:
The question has some details missing which I have shown in the attached file.
Explanation:
The concept of arrehenius equation is used to calculate the activation energy.
- Given T1 = 141.0 degree celsius = 414K and K1 = 3.3 x 10^8
- T2 = 77 degree celsius = 350K and k2 = 1.1 x 10^8
- from Arrehenius equation;
- ln(k2/k1) = -Ea/R [1/T2 - 1/T1]
- ln(1.1/3.3) = -Ea/8.314 [ 1/350 - 1/414]
- Ea = 20.679KJ/mol = activation energy for this reaction
The relationship between the energy of a photon (E) and the wavelength of the light (λ) is an inverse relationship and is described by the following by the equation: E=hcλE=hcλ where h is Planck's constant and c is the speed of light
Answer:
In solid
Explanation:
As a solid has very tightly packed molecules which move very difficulty and only vibrate
