A Reaction Has a Rate Constant, K = 2 $t_{1 / 2}$

A reaction has a rate constant, k = 2.55 × 10^-3 mol^-1 dm³ s^-1. Select all that apply.

A) It is a second order reaction.
B) Double the concentration of the reactant, will quadruple the reaction rate.
C) Its half life $t_{1 / 2}$ = 272 s.
D) Its concentration will decay faster than a first order reaction with the same initial rate.
