Question

The change in free energy accompainied by the isothermal reversible expansion of 1 mol of an ideal gas when it doubles its volume is `Delta G_(1)`. The change in free energy accompanied by sudden isothermal irreversible doubling volume of 1 mole of the same gas is `Delta G_(2)`. Ratio of `Delta G_(1)` and `Delta G_(2)` is
A. 1
B. `(1)/(2)`
C. `-1`
D. `-(1)/(2)`

Answer 1

Correct Answer - A
free energy is a state function .i.e. indpendent on the path followed
