An optically active compound 'A' upon acid catalysed hydrolysis yield two optically active compounds 'B' and 'C' by pseudo first order kinetics. The observed rotation of the mixture after 20 minutes was 5 degrees and after completion of reaction was -20 degrees. If optical rotation per mole of A, B and C are 60, 40 and -80 degrees. Calculate half life of the reaction.
