For the following reaction (dimerization with one elementary step): 2A → A2 the concentration of A in the reaction chamber at time zero was 0.2x10-3 mol L-1 , and concentration of A2 was zero. At time 200 s the concentration of A2 was 0.05x10-3 mol L-1 . (i) What is the order of this reaction? Explain your answer. (ii) Outline the differential and the integrated reaction rate laws for the above reaction. (iii) Calculate the reaction rate constant. (iv) Calculate the reaction time at which the concentration of A2 will be equal to 0.07x10-3 mol L-1 . Assume that the reverse reaction can be neglected.
