Place the atoms relative to each other. place the atom with group number in the center because it has the electronegativity. of atoms have the same group number, place the atom with the period number in the center.

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
