Homework Help: Statistical physics/Thermodynamical question

  1. Feb 8, 2005 #1
    I have a chemical reaction at equilibrium " cis <--> trans " at 300K
    The energydifference between the two states is 4,7 kJ/mol and cis has the highest energy. I want to find out how many molecules that is in cis- and how many that is in trans-state?

    Thankful for tips!

    Use one of the variations of Gibbs free energy equations and solve for the ratio
