1) The concentration of the reactant A in the reaction A → B at different times are given below Concentration (M) Time (minutes) 0.069 0 0.052 17 0.035 34 0.018 51 The rate constant of the reaction according to the correct order of reaction is A) 0.001 M/min B) 0.001 $min^{-1}$ C) 0.001 min/M D) 0.001 $M^{-1}min^{-1}$ Answer: Option AExplanation: $\because$ Rate remains constant. So, it is independent of concentration, the reaction is of zero order. According to rate law Rate = K.(conc.)° =0.001 M/min
