1.	Decomposition of H_2O_2 (Ist order) H_2O_2(aq)toH_2O(l)+1/2O_2(g) Can be monitored by titration method by pressure measurement.If {:("time(min.)",t=0,30,oo),("Pressure (mm of Hg)",200,375,400):} While when progress of same reaction was monitored by titration method or the volume of titrant consumed after 10 min was found to be 20 ml.Then complete the following table. {:("Time(min)",t=0,10,30),("Pressure(mm of Hg)",200,(b),(c )),("Volume of" KMnO_4,(a),20,(d)):} consumed (ml)
Answer» Solution :`k=1/(30"MIN")LN{(400-200)/(400-375)}=1/(30"min")ln{200/25}=(ln2)/T_(1//2)` `T_(1//2)=(30 "min")(ln2)/(ln8)=10` min So, we will have `{:("Time(min)",t=0,10,30),("Pressure (in MM of Hg)",200,300,375),("Volume of" KMnO_4"consumed (ML)",40,20,5):}`
