In a hypothetical reaction 2B aq C aq A aq 1st order decomposition A is optically active dextro rototory while B and C are optically inactive but B takes part in a titration reaction fast reaction with H O Hence the progress of reaction can be monitored by measuring rotation of plane of polarised light or by measuring volume of H O consumed in titration In an experiment the optical rotation was found to be 0 30 at t 20 min and 0 15 at t 50 min from start of the reaction If the progress would have been monitored by titration method volume of H O consumed at t 30 min from start is 30 ml then volume of H O consumed at t 90 min will be A 60 ml B 45 ml Le 5 52 5 ml D 90 ml
