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 . The half life period (minutes) of the reaction when the initial pressure is 16 bar at the same temperature is |

Answer» 120 `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) = (16)/(4)`. `(t_(1//2))_(2) = (16)/(4) XX 45` = 180 MIN |
