A reaction will be spontaneous only at low temperatures if both ΔH and ΔS are negative. For a reaction in which ΔH = - 320.1 kJ/mol and ΔS = - 86.00 J/K · mol. Determine the temperature (in °C) below which the reaction is spontaneous.

Is it possible for a balloon with an initial internal pressure equal to 250.0 kPa to naturally expand to four times its initial volume when the temperature remains constant and the atmospheric pressure is 101.3 kPa?
