Predit the rate law of the following reactions based on the data given below: 2A + B to C+D

Answer»

rate = `K[A][B]^(2)`
rate = `k[A]^(2)[B]`
rate `=k[A][B]`
rate `=k[A]^(2)[B]^(2)`

Solution :a) By comparing (i) and (II) reaction rate becomes double when [A] is made twice while [B] is KEPT CONSTANT
`therefore` ORDER w.r.t. [A]=1
By comparing (i) and (iii) reaction rate becomes four timew when [B] is made twice while [A] is made twice while [A] is kept constant
`therefore` order w.r.t. [B]=2 `therefore` rate `=k[A][B]^(2)`
