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 ฮต, where =ฮตร1.010โ24 j. in other words, each no2 group could have ฮต of rotational kinetic energy, or 2ฮต, or 3ฮต, and so forth โ 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 32ฮต. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ฮต. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
