5. A two-dimensional gas is one in which the speeds are distributed only in two directions, such as in the x and y directions. The Maxwell- Boltzmann speed distribution function for a two-dimensional gas is m mv2 g(v)dv= v exp dv KBT 2kBT For a two-dimensional gas at 25C calculate (a) Average energy per mole of the gas (b) Most probable energy per mole of the gas (c) Root-mean-square energy per mole of the gas The percentage of molecules that have an energy equal or greater than 10 kJ/mol.
