The Arrhenius parameters for the thermal decomposition of NaCl, 2NOCl(...
Arrhenius Parameters for Thermal Decomposition of NaCl
- The Arrhenius parameters for the thermal decomposition of NaCl, 2NOCl(g)2NO(g) CI2 are:
- A = 1013 M1s1
- E0 = 105 kJ mol1
- RT = 2.5 kJ mol1
Enthalpy of the Activated Complex
- The enthalpy (in kJ mol1) of the activated complex can be calculated using the Arrhenius equation:
k = Ae(-E0/RT)
- where k is the rate constant, A is the pre-exponential factor, E0 is the activation energy, R is the gas constant (8.314 J K-1 mol-1), and T is the temperature in Kelvin.
- Taking the natural logarithm of both sides of the equation, we get:
ln(k) = ln(A) - (E0/RT)
- Rearranging the equation, we get:
(E0/RT) = ln(A/k) + ln(k)
- Substituting the given values, we get:
(E0/RT) = ln(1013 M1s1/2) + ln(2.5 kJ mol1)
- Simplifying the equation, we get:
(E0/RT) = 20.83 + 1.10
- Therefore, the enthalpy (in kJ mol1) of the activated complex is:
(E0/RT) = 21.93 kJ mol1
- Rounded to the nearest whole number, the answer is:
(E0/RT) = 22 kJ mol1
- Therefore, the correct answer is option 'D' (100 kJ mol1).
- The Arrhenius parameters for the thermal decomposition of NaCl, 2NOCl(g)2NO(g) CI2 are:
- A = 1013 M1s1
- E0 = 105 kJ mol1
- RT = 2.5 kJ mol1
Enthalpy of the Activated Complex
- The enthalpy (in kJ mol1) of the activated complex can be calculated using the Arrhenius equation:
k = Ae(-E0/RT)
- where k is the rate constant, A is the pre-exponential factor, E0 is the activation energy, R is the gas constant (8.314 J K-1 mol-1), and T is the temperature in Kelvin.
- Taking the natural logarithm of both sides of the equation, we get:
ln(k) = ln(A) - (E0/RT)
- Rearranging the equation, we get:
(E0/RT) = ln(A/k) + ln(k)
- Substituting the given values, we get:
(E0/RT) = ln(1013 M1s1/2) + ln(2.5 kJ mol1)
- Simplifying the equation, we get:
(E0/RT) = 20.83 + 1.10
- Therefore, the enthalpy (in kJ mol1) of the activated complex is:
(E0/RT) = 21.93 kJ mol1

(E0/RT) = 22 kJ mol1
- Therefore, the correct answer is option 'D' (100 kJ mol1).
