For an ideal binary liquid mixture

Options

  1. A( H _ ( mix ) =0 ; S _ ( mix ) < 0 )
  2. B( S _ ( mix ) >0 ; G _ ( mix ) < 0 )
  3. C( S_ ( mix ) =0 ; G_ ( mix ) =0 )
  4. D( V _ ( mix ) =0 ; G _ ( mix ) >0 )

Correct answer

B. ( S _ ( mix ) >0 ; G _ ( mix ) < 0 )

Step-by-step solution

For an ideal binary liquid mixture S_ mix >0 and G_ mix < 0 For ideal solution; H_ mix =0 and V_ mix =0 G= H - T S G should be - ve for reaction to be spontaneous, that is, G < 0 . When G < 0 , then S should have value greater than zero
