- 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.arrow_forwardBased on the diagram in Exercise 12.83, which of the reactions has the fastest rate? Which has the slowest rate?arrow_forwardRank the following in order of increasing reaction rate. (a) Dynamite exploding (b) Iron rusting (c) Paper burningarrow_forward
