Inversion of sucrose (C12H22O11) is a first order reaction and is studied by measuring angle of rotation at different interval of time
r0 = angle of rotation at the start, rt = angle of rotation at time t
r = angle of rotation at the complete reaction
There is 50% inversion, when
  • a)
    r0 = 2rt - r
  • b)
    r0 = rt - r
  • c)
    r0 = rt - 2r
  • d)
    r0 = rt + r
Correct answer is option 'A'. Can you explain this answer?

r0 = rotation at the start, rt = rotation at time t
r = rotation at the end then (r - r0) = a and (r - rt) = (a - x)
When 50% inversion has taken place

∴  2 (a - x) = a
2(r - rt) = r - r0
2r - 2rt = r - r0
∴  r0 = (2rt - r)
