For the reaction A + B rarr P, the rate is given by Rate = K [A]^(1) [B]^(2). By how many times does the rate of reaction increase when concentrations of A & B are doubled?

Answer»

SOLUTION :`K_(1)=[A]^(1)[B]^(2)""rarr(1)`
`K_(2)=[2A]^(1)[2D]^(2)`
`K_(2)=[2A]4[D]^(2)`
`K_(2)=8[A]^(1)[D]^(2)`
`(K_(2))/(K_(1))=(8cancel([A]^(1)[D]^(2)))/(CANCEL([A]^(1)[D]^(2)))`
`K_(2)=8K_(1)`
The rate of reaction increase 8 times when concentration of A and B are doubled.
