Consider the second-order decomposition of nitroysl chloride: 2NOCl(g) ? 2NO(g) + Cl2(g) At 450 K the rate constant is 15.4 atm-1s-1. How much time (in s) is needed for NOCl originally at a partial pressure of 50 torr to decay to 18.6 torr? How much time (in s) is needed for NOCl originally at a concentration of 0.0155 M to decay to 0.0035 M?
