The following data were obtained at a certain temperature for the decomposition of ammonia in contact with tungsten:
p (m m Hg) 50 100 200
Relative `t_(1//2)` 3.64 1.82 0.91
Find the order of the reaction.

Explanation

We know ,
`((t_(1/2))1)/((t_(1/2))_(2))=((a_(2))/(a_(1)))^(n-1)" "...(Eqn .13)`
`(3.64)/(1.82) =((100)/50)^(n-1)`
`2=2^(n-1)`
`n -1 = 1 `
n = 2
