8.) Consider the following equilibrated system: 2NO2(g)=2NO(g) + O2(g). If the Kc value
is 0.918, find the equilibrium concentration of the O2 gas if the NO2 concentration is 0.520
M and the [NO] is 0.300 M at equilibrium. (2.76 M)
At high temperatures nitrogen (N2) and oxygen (O2) will react to form NO.N2(g) + O2(g) ⇆ 2 NO(g) (4.1)The value for the equilibrium constant for reaction 4.1 is KC = 2.7 x 10^-17 at some temperature T.A system initially has [N2] = 0.0800 M and [O2] = 0.0500 M. There is no NO initially present inthe system. Find the value for [NO] that will be present at equilibrium.
