Post Utme Rsu 2018 Chemistry Objective / Multiple Choice
Question 31 POST_UTME_RSU • 2018 • CHEMISTRY • objective

Determine the rate cons\tant (k) for the reaction: 2NO(g) + O2(g) → 2NO2(g), given that the initial concentrations of NO and O2 are 0.1 M and 0.05 M, respectively, and the rate of reaction is 0.02 M/s after 10 minutes.

Answer Options

Correct Answer A. \( k = \frac{2.303}{t} \log \frac{[NO]_0^2[O_2]_0}{[NO_2]_0^2} \)
B. \( k = \frac{2.303}{t} \log \frac{[NO]_0[O_2]_0}{[NO_2]_0} \)
C. \( k = \frac{2.303}{t} \log \frac{[NO]_0}{[NO_2]_0} \)
D. \( k = \frac{2.303}{t} \log \frac{[O_2]_0}{[NO_2]_0} \)
Correct Answer
A
Correct Option:
\( k = \frac{2.303}{t} \log \frac{[NO]_0^2[O_2]_0}{[NO_2]_0^2} \)
