Question 22 POST_UTME_GREENFIELD_UNIVERSITY • 2025 • CHEMISTRY • objective

Determine the equilibrium cons\tant (Kc) for the reaction: 2NO(g) + O2(g) ⇌ 2NO2(g), given that [NO] = 0.5 M, [O2] = 0.2 M, and [NO2] = 0.8 M.

Answer Options

Correct Answer A. \( K_c = \frac{[NO_2]^2}{[NO]^2 [O_2]} \)
B. \( K_c = \frac{[NO_2]}{[NO]^2 [O_2]} \)
C. \( K_c = \frac{[NO]^2 [O_2]}{[NO_2]^2} \)
D. \( K_c = \frac{[NO]^2 [O_2]^2}{[NO_2]^2} \)
Correct Answer
A
Correct Option:
\( K_c = \frac{[NO_2]^2}{[NO]^2 [O_2]} \)
