Statement-1 : The third law of thermodynamics implies that absolute zero cannot be reached.
Statement-2 : `Delta G^(@)` for an ideal gas reaction is a function of temperature.
Statement-3 : The adiabatic expansion of a gas into a vacuum is spontaneous.

Text Solution

Verified by Experts

As efficiency `eta_2 = 1-T_2/T_1" ":." "`It equals to 1 only when `T_2/T_1 = 0` or `T_2 = 0K`
But absolute zero is not possible. So, Carnot engine cannot have 100% efficiency.
