When sucrose is hydrolyzed it produced dextro-rotatory "glucose " and leavo-rotatory "fructose" whereas reactant itself is a dextro-rotatory compound. The above conversion process follows first order kinetics. Similarly an optically active compound A hydrolyzed as follows : A+ H_(2) O overset( H^(+))(rarr) 2B + C The observed rotation of compound A,B and C are 60^(@), 50^(@) and - 80^(@) per mole respectively. The angle of rotation after 40 minutes and after the completion of reaction were 26^(@) and 10^(@)respectively at 27^(@)C and activation energy for conversion is 27kJ mol^(-1) . At what temperature half life of above process is equal to 31.1 minutes.
