For any acid catalysed reaction, `Aoverset(H^(+))rarrB`
half- life period is independent of concentration of A at given pH. At definite concentration of A half- time is 10min at pH=2 and half- time is 100 min at pH=3. If the rate law expression of reaction is `r=k[A]^(x)[H^(+)]^(y)` then calulate the value of (x+y).
