    Maybe try to explain it by using Gibbs free energy equation?

    G=H -TS (so the free energy is equal to enthalpy change - (temp (in kelvin) times by entropy change)) for the reaction to be feasible/spontaneous G<0 less than zero (if I remember correctly). You can use this to link entropy and temperature to the feasibility of a reaction.

    Feasibility determined by value of G. As poster above said, for a reaction to be feasible it has to be less than 0. Try plugging in different numbers for T and S and playing around with it to understand the effects it has.
