Homework Statement
A 1.0 dm3 reaction vessel contains initially 1.0 mol of N2O4(g) and 1.0 mol of NO2(g).
At equilibrium, 0.75mol of N2O4(g) are present.
What is the value of Kc?
A. 0.33
B. 0.50
C. 2.0
D. 3.0
The Attempt at a Solution
Right answer = D, but I do not why. My attempt for Kc is (3/4)^2 / (9/8) = 0.5, so wrong answer. Please, help me with this stricky one.
