At equilibrium, the ﬂask contains 8.65 g CH3OH. Calculate the equilibrium constant (Kc) for the reac-on at this temperature. Consider the following reac,on: N2 O4 (g) ⇌ 2 NO2 (g) Kc = 0.36 A reac,on mixture ini,ally contains 0.100 M NO2 and 0.0100 M N2O4. Find the equilibrium concentra,ons of N2O4 and NO2. ax 2 + bx + c = 0 −b ± b 2 − 4 ac x= 2a Consider the following reac,on: N2 O4 (g) ⇌ 2 NO2 (g)...
