Problem

The following data were obtained in an experiment on inversion of cane sugar, which follows first-order kinetics:

Time (min)	$0$	$10$	After a long time
Total angle of rotation (degree)	$+40$	$+15$	$-10$

The rate constant in

\text{s}^{-1}

is (a)

0.0693

(b)

1.15\times10^{-3}

(c)

0.693

(d)

1.15\times10^{-2}
