Which of the following is/are correct for the first order reaction? (a is initial concentration of reactant, x is concentration of the reactant reacted and t is time)

Options

  1. AI and II only
  2. BII and III only
  3. CI, II and III only
  4. DI and III only

Correct answer

C. I, II and III only

Step-by-step solution

I log (a - x) (where a - x is the remaining concentration), decreases with the passage of time. II k t = 2.303 log ⁡ a a - x III For first order t 1 2 is independent of a
