Chapter 12: Q68 E (page 710)
Why are elementary reactions involving three or more reactants very uncommon?
The reaction rate depends on the number and orientation of collisions between the reactant molecules.

Iodine-131 is a radioactive isotope that is used to diagnose and treat some forms of thyroid cancer. Iodine-131 decays to xenon-131 according to the equation:I-131⟶Xe-131 + electron. The decay is first-order with a rate constant of 0.138 d−1. All radioactive decay is first order. How many days will it take for 90% of the iodine−131 in a 0.500 M solution of this substance to decay to Xe-131?
Based on the diagrams in Exercise 12.83, which of the reactions has the fastest rate? Which has the slowest rate?
(a) Multiply 2.334 cm and 0.320 cm.(b) Divide 55.8752 m by 56.53 s.
From the following data, determine the rate law, the rate constant, and the order with respect to A for the reaction \({\bf{A}} \to {\bf{2C}}\).
Doubling the concentration of a reactant increases the rate of a reaction four times. With this knowledge, answer the following questions:
