Question

8. If equilibrium constant is 2 atm at 300 K then
the standard free energy change at 300 K
V and 1 atm pressure is [NCERT Pg. 187]
(1) 1728.9 J mol-1
(2) -1728.9 J mol-1
(3) 309 J mol-1
(4) -309 J mol-1​

Answer 1

Answer:

the answer is 1728.9j mol-1

Answer 2

Given, that the equilibrium constant $K = 2 atm$ at $300K$

Pressure $P= 1atm$

We know,

$\Delta G$°$= -RTln(K)$

$=-8.314\times 300\times \ln(2)\\=-1728.9 J mol^{-1}$
