A first order reaction is 50 % completed in 1.26 10¹⁴ ~s . How much time would it takes for 100 % completion?

Options

  1. A1.26 10¹⁵ ~s
  2. B2.52 10¹⁴ ~s
  3. C2.52 10²⁸ ~s
  4. DInfinite

Correct answer

D. Infinite

Step-by-step solution

k -for first order. 0.693 t_ 1 / 2 = 0.693 1.26 10¹⁴ for 100 % completion. t= 2.303 k a a-x t= 2.303 1.26 10¹⁴ 0.693 100 0 t=
