Question

 Which of the following statements is /are false? 

(A) ∆S for 2/3 N₂ (g) × N (g) is positive 

(B) ∆G_system is always zero for a reversible process in a closed system 

(C) ∆G° for an ideal gas is a function of temperature and pressure 

(D) Entropy of a closed system is always maximized at equilibrium

Answer 1

Correct option (B, C, D)    

Explanation:

∆S for 1/2 H₂ → N is + ve true as no. of molecules yes, entropy increase

∆G_system is O for reversible process act standard conditions 

∆G° i real = VdP – sdT

Function of P,V,T not just P and T at equilibrium ∆G is moles 

Nothing fixed about ∆S
