Condensation is conversion from gas to liquid.
This process releases heat.
So, this is exothermic. ΔH is negative
Converting a gas to liquid will decrease the entropy as entropy of gas is greater than the entropy of liquid. ΔS is negative.
Since,
ΔG = ΔH - T*ΔS,
ΔG would be negative at lower temperature.
So, reaction is spontaneous at low temperatures
