For a reaction 1 2 A 2 B , rate of disappearance of ' A ' is related to the rate of appearance of 'B' by the expression

Options

  1. A- d [ A ] dt = 1 2 d [ B ] dt
  2. B- d [ A ] dt = 1 4 d [ B ] dt
  3. C- d [ A ] dt = d [ B ] dt
  4. D- d [ A ] dt =4 d [ B ] dt

Correct answer

B. - d [ A ] dt = 1 4 d [ B ] dt

Step-by-step solution

aligned & 1 2 ~A 2 ~B & -2 ~d [ ~A ] dt =+ d [ B ] 2 dt & - d [ A ] dt = 1 4 d [ B ] dt aligned
