Question 16 POST_UTME_FUTA • 2025 • CHEMISTRY • objective

The rate cons\tant (k) for a first-order reaction is given by the equation: k = Ae^\( -Ea/RT \). If the activation energy (Ea) is 100 kJ/mol, the gas cons\tant (R) is 8.314 J/\( mol*K \), and the temperature (T) is 298 K, what is the value of the pre-exponential factor (A) if the rate cons\tant (k) is 0.05 s^\( -1 \)?

Correct Answer A. 1.33 x 10^11 s^\( -1 \)

B. 1.33 x 10^10 s^\( -1 \)

C. 1.33 x 10^9 s^\( -1 \)

D. 1.33 x 10^8 s^\( -1 \)

Correct Answer

Correct Option:

1.33 x 10^11 s^\( -1 \)
