× 10^12 s^-1 and an activation energy of 150 kJ/mol, calculate the rate constant at 298 K.
The rate constant (k) can be calculated using the Arrhenius equation:
k = A e^(-Ea/RT)
where A is the pre-exponential factor, Ea is the activation energy, R is the gas constant (8.314 J/mol*K), and T is the temperature in Kelvin.
Plugging in the values given:
A = 2.17 × 10^12 s^-1
Ea = 150 kJ/mol = 150,000 J/mol
R = 8.314 J/mol*K
T = 298 K
k = 2.17 × 10^12 s^-1 e^(-150,000 J/mol / (8.314 J/mol*K * 298 K))
Simplifying:
k = 2.17 × 10^12 s^-1 e^(-50.59)
k = 2.17 × 10^12 s^-1 * 1.81 × 10^-23
k = 3.93 × 10^-11 s^-1
Therefore, the rate constant for the gas phase unimolecular reaction at 298 K is 3.93 × 10^-11 s^-1.
