For the inversion of cane sugar, (C12H22O11) obeying I order following data were obtained.
Time (min.) | 0 | 10 | ∞ |
Angle of rotation of solution(degree) | +20 | −2.5 | −10 |
Since inversion of sugar is first order reaction, value of k is given by:
⟹k=1tlnro−r∞rt−r∞
⟹k=110ln20−(−10)(−2.5)−(−10)
⟹k=ln4=0.14
