For a hypothetical reaction, the following kinetic data suggested that the overall order of this reaction is {:("[A]",[B],[C]),(mol" "dm^(-3),mol" "dm^(-3),mol" " dm^(-3) s^(-1)),(2.0,1.0,1.0),(2.0,4.0,2.0),(1.0,4.0,1.0):}

3
1.5
1
0.5

Solution :LET rate of reaction , `R=[A]^(a) [B]^(b)`
`1=(2)^(a)(1)^(b)""…(i)`
`2=(2)^(a)(1)^(b)""…(ii)`
`1=(1)^(a)(4)^(b)""…(iii)`
Dividing (ii) by (i)
`((2)^(a)(4)^(b))/((2)^(a)(1)^(b))=(2)/(1)`
`4=2 to b=1//2`
Dividing (ii) by (iii)
`((2)^(a)(4)^(b))/((1)^(a)(4)^(b))=(2)/(1)`
`2^(a) = 2 IMPLIES a=1`
`therefore` Rate law EXPRESSION is , `r=[A][B]^(1//2)`
Order of reaction `=1+(1)/(2)=(3)/(2)=1.5`
