Question
Two nitro (NO₂) groups are chemically bonded to a patch of surface. They can't move to another location on the surface, but they
can rotate (see sketch at right).
It turns out that the amount of rotational kinetic energy each NO₂ group can have is required to be a multiple of a, where
* = 1.0 × 10-24 J. In other words, each NO₂ group could have & of rotational kinetic energy, or 2, or 3, and so forth - but it
cannot have just any old amount of rotational kinetic energy.
Suppose the total rotational kinetic energy in this system is initially known to be 68. Then, some heat is removed from the
system, and the total rotational kinetic energy falls to 64€. Calculate the change in entropy.
Round your answer to 3 significant digits, and be sure it has the correct unit symbol.
