Entropy Calculation:
The entropy of activation (ΔS‡) can be calculated using the Arrhenius equation:
ΔS‡ = -R * ln(A)
where R is the gas constant (8.314 J/mol∙K) and A is the pre-exponential factor (1 x 10^13 M^-1s^-1).
Plugging in the values, we get:
ΔS‡ = -8.314 * ln(1 x 10^13)
ΔS‡ ≈ -8.314 * 23.03
ΔS‡ ≈ -191.48 J/mol∙K
Enthalpy Calculation:
The enthalpy of activation (ΔH‡) can be calculated using the Arrhenius equation:
ΔH‡ = Ea + RT
where Ea is the activation energy (104 kJ/mol), R is the gas constant (8.314 J/mol∙K), and T is the temperature (300 K).
Plugging in the values, we get:
ΔH‡ = 104 + 8.314 * 300
ΔH‡ ≈ 104 + 2494.2
ΔH‡ ≈ 2598.2 kJ/mol
Free Energy of Activation Calculation:
The free energy of activation (ΔG‡) can be calculated using the equation:
ΔG‡ = ΔH‡ - TΔS‡
Plugging in the values we calculated earlier, we get:
ΔG‡ = 2598.2 - 300 * (-191.48)
ΔG‡ ≈ 2598.2 + 57444
ΔG‡ ≈ 60042.2 kJ/mol
Therefore, at 300 K, the entropy of activation is approximately -191.48 J/mol∙K, the enthalpy of activation is approximately 2598.2 kJ/mol, and the free energy of activation is approximately 60042.2 kJ/mol for the thermal decomposition of NOCl.

ΔH‡ ≈ 104 + 2494.2
ΔH‡ ≈ 2598.2 kJ/mol
Free Energy of Activation Calculation:
The free energy of activation (ΔG‡) can be calculated using the equation:
ΔG‡ = ΔH‡ - TΔS‡
