Calculate the order of reaction form the following data:
`2NH_(3) rarr N_(2) + 3H_(2)` (reaction)
`|{:("Pressure (mm Hg)",50,100,200),("Half lives (min)",3.52,1.82,0.93):}|`

Explanation

We know
`n = 1+(log(t_(1//2))_(1)-log(1_(1//2))_(2))/(logp_(2)-logp_(1))`
`= 1+ (log 3.52 - log 1.82)/(log 100 - log 50)`
`= 1.95 ~~ 2`
ismilarly, we calculate for other set conditions also.
