Question

Match the following list : List - I (Order of reaction) Assume single reactant is involved in rate law (nA → B)] List - II (Characteristics) (P) 0 (1) Half life remains constant throughout. (Q) 2 (2) Second half life is double of first. (R) 1 (3) Reaction gets completed in finite time. (S) 3 (4) Graph of log (rate of reaction) vs log (conc. of reactant) will have a slope equal to 3 . (5) Reaction must be complex.

Reactions with order ≤ 1 get completed in finite time. First-order reactions have a constant half-life. t 1/2 ​ ∝ a 0 ​ 1 ​ f orseco n d or d err R a t e = k [ A ] n ∴ lo g ( r a t e ) = lo g k + n lo g A ∴ s l o p e = n
