Consider the following statements: In general, the rate of a chemical reaction increases a bit at first because it takes a while for the reaction to get warmed up. After that, however, the rate of the reaction decreases because its rate is dependent on the concentrations of the reactants, and these are decreasing. Indicate everything that is correct in these statements, and indicate everything that is incorrect. Correct the incorrect statements and explain.
Two isomers (A and B) of a given compound dimerize as follows: 2Ak1A22Bk2B2 Both processes are known to be second order in reactant, and k1 is known to be 0.250 L/mol s at 25C. In a particular experiment A and B were placed in separate containers at 25C, where [A]0 = 1.00 102M and [B]0 = 2.50 102 M. It was found that after each reaction had progressed for 3.00 min, [A] = 3.00[B]. In this case the rate laws are defined as Rate=[A]t=k1[A]2Rate=[B]t=k2[B]2 a.
