For a reaction to be spontaneous under standard conditions at all temperatures, the signs of δh° and δs° must be __________ and __________, respectively.

  • Dejanras: For a reaction to be spontaneous under standard conditions at all temperatures, the signs of ΔH° and ΔS° must be negative and positive, respectively.
    Gibbs free energy (G) determines if reaction will proceed spontaneously, if ΔG is negative, reaction is spontaneous.
    ΔG = ΔH - T·ΔS.
    ΔG - changes in Gibbs free energy.
    ΔH - changes in enthalpy.
    ΔS - changes in entropy.
    T is temperature in Kelvins.
