Question

26.) The molar free energy (J mol-) of a liquid solution
of a binary A-B alloy as a function of temperature (T)
and composition (x, the mole fraction of B ) is given
by GP (T ,x)=(1 – x)G%+ +x6%+ +
RT [x In x + (1 - x)]+4000 x (1 - x).
where, G%2 and 6%, are the molar free energies of
pure liquid A and pure liquid B.
What is the excess molar free energy, GAS-, for an
alloy with x =05 at T =1000 K ?
Take, gas constant, R=8314J K-mol-
(a) 1000J mol-
(b) -2000J mol-
(c) 4763J mol-1
(d) -5763J mol-1​

Answer 1

a) 1000j

Explanation:

I don't know the answer.
