The decomposition of ammonia on tungsten surface at 500 K follows zero order kinetics. The half-life period of this reaction is 45 minutes when the initial pressure is 4 bar. Find the half-life period (in minutes) of the reaction when the initial pressure is 16 bar at the same temperature. |

Answer» `t_(1//2) PROP a_(0)` (initial concentration or initial pressure) `(t_(1//2))_(1) prop P_(1)` `(t_(1//2))_(2) prop P_(2)` `(t_(1//2))_(2)/(t_(1//2))_(1) = P_(2)/P_(1), (t_(1//2))_(2)/45 = 16/4` `(t_(1//2))_(2) = 16/4 xx 45 = 180` MIN |
