1.

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
