Chapter 12, Problem 58E
In an experiment, a sample of NaClO3 was 90% decomposed in 48 min. Approximately how long would this decomposition have taken if the sample had been heated 20 °C higher? (Hint: Assume the rate doubles for each 10 °C rise in temperature.)

Laser. Indicate the relationship between metastable state and stimulated emission.
The table includes macrostates characterized by 4 energy levels (&) that are
equally spaced but with different degrees of occupation.
a) Calculate the energy of all the macrostates (in joules). See if they all have
the same energy and number of particles.
b) Calculate the macrostate that is most likely to exist. For this macrostate,
show that the population of the levels is consistent with the Boltzmann
distribution.
