At the temperature of 1450 °c the equilibrium constant of the reaction n2(g) + o2(g) = 2no(g) is kc= 0,0900
calculate the molar concentrations to the equilibrium knowing that the initial mixture contains 1.00 mol of n2 and 1.00 mol of o2 in a volume of 5.00 l.

solutions: (0,142 mol/l; 0,142 mol/l; 0,116 mol/l)
