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