Inversion of a sugar follows first order rate equation which can be followed by noting the change in rotation of the plane of polarization of light in the polarimeter if r_infty,r_t and t=oo, t=t and t=0, then, first order reaction can be written as:

Answer»

`K=1/t"LOG"(r_1-r_infty)/(r_0-r_infty)`
`K=1/tIn(r_0-r_oo)/(r_t\-r_oo)`
`K=1/tIn(r_oo-r_0)/(r_oo\-r_t)`
`K=1/tIn(r_oo-r_1)/(r_oo\-r_0)`
