Answer:
v= 103.5 V; energy =1.65 x 10^-17
Explanation:
the deflected energy eV sin θ
Energy of a random atomic and molecular is called molecules energy
Answer:
53/14
Explanation:
average acceleration = (Vfinal -Vintial)/ time taken
That's the definition of pressure ... force on a given area.
So when that force increases, it's an increase in pressure.
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>
