Answer»

The optical rotation of cane sugar in $0.5 N$ lactic acid at $25^{o} C$ at various time intervals are given below

Time (min)	0	1435	11360	$\infty$
Rotation ( $^{o}$ )	34.50	31.10	13.98	-10.77

Predict the rate constant expression for the given first order reaction.

Here,

r_{0}

is the optical rotation at time = 0

r_{t}

is the optical rotation at time = t

r_{\infty}

is the optical rotation at time =

\infty
