In the reaction `aArarr bB ` , the rate of disappearance of A and the rate of formation of B at a given time are x and `1.5 " xmol.L"^(-1).s^(-1)` respectively . Establish the relation between 'a' and 'b'.

Text Solution

Verified by Experts

`-(1)/(a)(d[A])/(dt)=(1)/(b)(d[B])/(dt)`
As, `-(d[A])/(dt)=" xmol"^(-1).s^(-1) and (d[B])/(dt)=1.5" xmol"^(-1).s^(-1)`
`therefore(x)/(a)=(1.5x)/(b) " or, " (1)/(a)=(3)/(2b) " or," 3a=2b`
