The rate (r) of a chemical reaction is plotted against time (t) in graph 1. The initial rate of the reaction is r0. The plot of ln(r/r0) with time is shown in graph 2. The correct statements are: [Multi-Correct Question]
(1) Initial concentration of the reactant is 500 mol L-1.
(2) Both the graphs represent the kinetics of a first-order reaction.
(3) After 69.3 s, the concentration of the reactant will be reduced to (1/32) times of its initial concentration.
(4) The rate (r) always decreases with time irrespective of the order of the reaction.
[Ans: (1),(2),(3)]
