Post Utme Veritas University 2023 Chemistry Objective / Multiple Choice
Question 21 POST_UTME_VERITAS_UNIVERSITY • 2023 • 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 \( t1/2 \) by the equation: k = ln(2) / t1/2.

Answer Options

Correct Answer A. \( k = \frac{ln\( 2 \ \)}{t_{1/2}} = \frac{ln(2)}{10} )
B. \( k = \frac{ln\( 2 \ \)}{t_{1/2}} = \frac{ln(2)}{20} )
C. \( k = \frac{ln\( 2 \ \)}{t_{1/2}} = \frac{ln(2)}{30} )
D. \( k = \frac{ln\( 2 \ \)}{t_{1/2}} = \frac{ln(2)}{40} )
Correct Answer
A
Correct Option:
\( k = \frac{ln\( 2 \ \)}{t_{1/2}} = \frac{ln(2)}{10} )
