The inverison of a sugar follows first order rate equation which can be followed by noting the change in the rotation of the plane of polarization of light in the polarimeter. If `r_(oo), r_(f)` and `r_(0)` are the rotations at `t = oo, t = t`, and `t = 0`, then the first order reaction can be written as

A

`k = (1)/(t)log.(r_(1)-r_(oo))/(r_(o) -r_(oo))`

B

`k = (1)/(t)ln.(r_(0)-r_(oo))/(r_(t)-r_(o))`

C

`k = (1)/(t)ln.(r_(oo)-r_(o))/(r_(oo)-r_(t))`

D

`k = (1)/(t)ln.(r_(oo)-r_(t))/(r_(oo)-r_(0))`
