Question

0 L mol ] A [ min t / 0.100 0.025 For a given reaction R P, T½ is related to [A]0 as given in table. Given: log 2 = 0.30 Which of the following is true? A. The order of the reaction is ½. B. If [A]0 is M, then T½ is 200 min. C. The order of the reaction changes to 1 if the concentration of reactant changes from 0.100 M to 0.500 M. D. t½ is 800 min for [A]0 = 1.6 M. Choose the correct answer from the options given below:

(A) A and C only
(B) A, B and D only
(C) C and D only
(D) A and B only
