At a certain temperature, the half change period for the catalytic decomposition of ammonia were found as follows:
Pressure (Pasacals) 66667 133333 266666
Half life period: 3.52 1.92 1.0 Calculate the order of reaction

Options

A. 3
B. 2
C. 0
D. 1

Answer

B

Explanation

`(t_(1//2))/(t_(1//2))_(2)=(a_(2))/(a_(1))^(n-1)` where n is order of reaction
From the given data `(3.82)/(1.92)=(1333)/(6667)^(n-1)`
