When sucrose , C_(12)H_(22)O_(11) , is dissolved in H_(2)O in the presence of an acid catalyst it reacts according to the equation C_(12)H_(22)O_(11) rarr 2C_(6)H_(12)O_(6) with a rate law of Rate =k [C_(12)H_(22)O_(11)] . If 3.00 g of sucrose decreases to 2.70 g in 2.50 hours in the presence of a certain concentration of an acid catalyst, what is the half -life for this reaction under these same condition?

BaO_(2)+H_(2)SO_(4) rarr BaSO_(4)+H_(2)O_(2) In the above method of preparation of H_(2)O_(2) , now-a-days H_(3)PO_(4) (conc.) is used instead of conc. H_(3)SO_(4) because :
