Molecular Energy With Relation to Number of Molecules

  1. Aug 31, 2015 #1
    1. The problem statement, all variables and given/known data
    Which solid-line curve most accurately represents the distribution of molecular energies in a gas at 500 K if the dotted-line curve represents the corresponding distribution for the same gas at 300 K?

    2. Relevant equations
    -

    3. The attempt at a solution
    Not sure how this works.
    Higher the temperature, more the energy, so that rules out (D)
    But that still leaves options A,B and C
