A zero-ordér reaction, A Product, with an initial concentration [ A ]₀ has a half-life of 0.2 ~s . If oné starts with thee concentration 2[ ~A ]₀ , then the half=life is =

Options

  1. A0.1 ~s
  2. B0.4 ~s
  3. C0.2 ~s .
  4. D0.8 ~s

Correct answer

B. 0.4 ~s

Step-by-step solution

t _ 1 / 2 1 a ^ n -1 for zero order reaction n =0 so t _ 1 / 2 a so array l (t_ 1 / 2 )₁ (t_ 1 / 2 )₂ = a₁ a₂ .2 (t_ 1 / 2 )₂ = [A₀ ] 2[A]₀ t_ 1 / 2 =.4 sec array
