At 300 K the half-life of a sample of a gaseous compound initially at 1 atm is 100 sec. When thepressure is 0.5 atm the half-life is 50 sec. The order of reaction is:(a) o65.(b) 1(c) 2(d) 3 |

Answer» we can se that half life is directly proportional to the pressure ( amount of gas) => t½ ∞ [A] so, order is 0 option a |
