The scientist who discovered the first real evidence of the big bang was EDWIN HUBBLE.
Astronomer Edwin Hubble was an American astrophysicist. He contributed in so many ways to humanity during his lifetime. One of his contribution is that, his observation showed the existence of galaxies that are far beyond the milky way; these galaxies were moving away from one another. This observation serves as a concrete evidence for the big bang theory, which explain the origin of the universe.
The answer to that question would be Activation energy. If would like me to elaborate just let me know. :)

Answer:
K(79°C) = 1.906 E7 s-1
Explanation:
Arrhenius eq:
∴ A = 5.0 E9 s-1
∴ Ea = 16.3 KJ/mol
∴ R = 8.314 E-3 KJ/K.mol
∴ T = 79°C ≅ 352 K ⇒ K = ?
⇒ K(79°C) = (5.0 E9 s-1)e∧[ - (16.3KJ/mol)/(8.314 E-3 KJ/K.mol)(352 K)]
⇒ K(79°C) = (5.0 E9 s-1)e∧(- 5.5697)
⇒ K(79°C) = (5.0 E9 s-1)*(3.811 E-3)
⇒ K(79°C) = 1.906 E7 s-1
Answer : The volume of 1 mole of 
and 
gases are the same.
Solution: Given,
Moles of = 1 mole
Moles of = 1 mole
Moles of 
= 2 mole
Formula used for ideal gas is :
P V = n R T
According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.
The moles of are more than the moles of and . So, the volume of will be more.
And the moles of and are equal. Therefore, their volumes are also equal.
Therefore, the best option is the volume of 1 mole of and gases are the same.
