For the decomposition of a compound AB at 600 K, the following data were obtained. The order of the decomposition of AB is

Answer»

0
1
2
1.5

Solution :Let rate equation be

rate `=k[AB]^(n)`
CASE (i) `2.75xx10^(-8)=k[0.2]^(n)`
Case (II) `11xx10^(8)=k[0.40]^(n)`
Case (iii) `24.75xx10^(-8)=k[0.6]^(n)`
DIVIDE ii by I
`=(11xx10^(-8))/(2.75xx10^(-8))=([0.40]^(n))/([0.2]^(n))`
`implies2^(n)=4impliesn=2:.` ORDER of reaction is 2.
