Question 36 POST_UTME_BOWEN_UNIVERSITY • 2017 • CHEMISTRY • objective

Determine the rate cons\tant (k) for the reaction: A → B + C, given that the initial concentration of A is 0.1 M, and after 10 minutes, the concentration of A has decreased to 0.05 M. The rate cons\tant is related to the half-life \( t1/2 \) of the reaction by the equation: k = ln(2) / t1/2.

Answer Options

A. \( k = 0.693 / 10 \) min^\( -1 \)
Correct Answer B. \( k = 0.693 / 5 \) min^\( -1 \)
C. \( k = 0.693 / 15 \) min^\( -1 \)
D. \( k = 0.693 / 20 \) min^\( -1 \)
Correct Answer
B
Correct Option:
\( k = 0.693 / 5 \) min^\( -1 \)
