Question 11 POST_UTME_BELLS_UNIVERSITY • 2018 • CHEMISTRY • objective

Determine the rate cons\tant (k) for the first-order reaction: ln\( [A]t/[A]0 \) = -kt, given that the initial concentration of A is 0.1 M and the concentration at time t is 0.01 M.

Answer Options

Correct Answer A. \( k = \frac{1}{t} lnleft\( \frac{[A]_0}{[A]_t}\right \ \) )
B. \( k = \frac{1}{[A]_0} lnleft\( \frac{[A]_t}{[A]_0}\right \ \) )
C. \( k = \frac{1}{t} lnleft\( \frac{[A]_t}{[A]_0}\right \ \) )
D. \( k = \frac{1}{[A]_t} lnleft\( \frac{[A]_0}{[A]_t}\right \ \) )
Correct Answer
A
Correct Option:
\( k = \frac{1}{t} lnleft\( \frac{[A]_0}{[A]_t}\right \ \) )
