1. A cube of aluminum 1.0 cm on each edge is placed into 9-M NaOH(aq), and the rate at which H2 gas is given off measured. a. By what factor will this reaction rate change if the aluminum cube is cut exacly in half and the two halves are placed in the solution? Assume that the reaction rate is proportional to the surface area, and thatall of the surface of the aluminum is in contact with the NaOH(aq). b. If you had to speed up this reaction as much as you could without raising the temperature, what would you do to the aluminum?
