SUMMARY
The calculation of the partial pressure of NOCl in the reaction 2NO (g) + Cl2 (g) ⇌ 2NOCl (g) can be accurately performed using the equilibrium constant Kp, which is given as 6.5×104. By applying the formula Kp = (PNOCl)2 / ((PNO)2 * (PCl2)), and substituting the known values of PNO = 0.35 atm and PCl2 = 0.10 atm, the correct calculation for PNOCl is PNOCl = √((6.5×104) * (0.35)2 * (0.10)). This method is confirmed as valid by participants in the discussion.
