The following data were obtained in an experiment on inversion of cane sugar (a first order kinetics)
Time (min)
\( 0 \quad 10 \) After a long time
Total angle of rotation (degree) \( +40+10 \quad-10 \)
The rate constant (in second \( { }^{-1} \) ) \( [\ln 2=0.693] \)
(a) 0.0693
(b) \( 1.52 \times 10^{-3} \)
(c) 0.693
(d) \( 1.15 \times 10^{-2} \)
