A. Reaction is spontaneous at (a) and (b)
B. Reaction is at equilibrium at point (b) and non-spontaneous at point (c)
C. Reaction is spontaneous at (a) and non-spontaneous at (c)
D. Reaction is non-spontaneous at (a) and (b)
Answer
2
Explanation
For, Spontaneous process $\mathrm{dG}<0$
For, Equilibrium $\mathrm{dG}=0$
For, Nonspontaneous process $\mathrm{dG}>0$
$\therefore $ A Wrong
B Correct
C Correct
D Wrong
For, Equilibrium $\mathrm{dG}=0$
For, Nonspontaneous process $\mathrm{dG}>0$
$\therefore $ A Wrong
B Correct
C Correct
D Wrong
