Question

The inversion of cane sugar is tracked using a polarimeter. Let the optical rotation angles be $r_0$, $r_t$, and $r_\infty$ at times zero, $t$, and infinity respectively. Which formula accurately determines the pseudo-first-order rate constant $k$?

Prashant Kotian · Accepted Answer

Correct answer: B. The total initial concentration is proportional to the total achievable optical shift . The concentration of unreacted sugar remaining is strictly proportional to the remaining optical shift . The log ratio of these quantities gives the correct equation.
