In your own words differentiate Comets Asteroids Meteors Meteoroids and Meteorites​
Eddi Din [679]

Thanks for the question,

Asteroids: These are rocky and airless plates from the formation of planets in our solar system. It basically revolves around our sun in the space barrier between Mars and Jupiter and moves in the size of cars to smaller planets.

Comets: comets are the most polluted glaciers of ice and dust created at the time of the birth of the solar system 4.6 billion years ago. Many comets have a fixed orbit around the outer surface of the solar system beyond the planet Neptune.

Meteoroids, Meteorites, Meteorites: Meteoroids are small asteroids or broken comet fragments and sometimes planets. They vary in size from sand dune to three large stones in diameter. When meteoroids collide with the earth's atmosphere, they form meteors. When those meteors survive space and reach the surface of the planet, their remains are called meteorites.

The rate constant of a chemical reaction increased from 0.100 s−1 to 3.10 s−1 upon raising the temperature from 25.0 ∘C to 51.0
forsale [732]

Answer:

A. (1/T₂ - 1/T₁) = -2.69 x 10⁻⁴ K⁻¹

B. ln (k₁/k₂) = -3.434

C. E = 106.13 KJ/mol

Explanation:

Part A:

we have:

T₁ = 25°C = 298 K

T₂ = 51°C = 324 K

(1/T₂ - 1/T₁) = (1/324 k - 1/298 k)

<u>(1/T₂ - 1/T₁) = -2.69 x 10⁻⁴ K⁻¹</u>

<u></u>

Part B:

ln (k₁/k₂) = ln (0.1/3.1)

<u>ln (k₁/k₂) = -3.434</u>

Part C:

The activation energy can be found out by using Arrhenius Equation:

ln (k₁/k₂) = E/R  (1/T₂ - 1/T₁)

where,

E = Activation Energy

R = General Gas Constant = 8.314 J/mol.k

Therefore,

-3.434 = (E/8.314 J/mol.k)(-2.69 x 10⁻⁴ K⁻¹)

<u>E = 106134.8 J/mol = 106.13 KJ/mol</u>
