The equilibrium system N2O4(g) 2NO2(g) was established in a 1.00-liter vessel. Upon analysis, the following information was found: [NO2] = 0.500 M; [N2O4] = 0.0250 M. What is the value of Keq?
google khan academy they have chemistry videos i hope they have what you need
N2O4 ==> 2NO2
Set up an ICE chart and substitute into the Keq expression. Solve for Keq. Post your work if you need additional help.
[N2O4] = 0.0250 M. What is the value of Keq
