The correct option is B A and B
We know, ΔG0=−RTlnK
⇒ΔH0−TΔS0=−RTlnK
⇒−ΔH0RT+ΔS0R=lnK
From this equation, the slope of the graph of lnK vs 1T is −ΔH0R, but since it is an exothermic reaction, the slope should be positive.
Hence the lines that correctly show the temperature dependence of equilibrium constant K, for an exothermic reaction are A and B.
