1.	The catalysed decomposition of H_(2)O_(2) in aqueous solution is followed by removing equal volume samples at various time intervals and titrating them with "KMnO"_(4) to determine the undecomposed H_(2)O_(2). The results thus obtained are : {:("Time (seconds)",,,:,,,0,,,600,,,1200),("cm"^(2)" of KMnO",,,:,,,22.8,,,13.8,,,8.2):} Show that the reaction is mono-molecular. What is the value of the specific reaction rate ?
