Question

# Which of the following lines correctly show the temperature dependence of equilibrium constant K, for an exothermic reaction?A and D A and B B and C C and D

Therefore ln K vs 1/T the graph will be a straight line with slope equal to $-\frac{∆{H}^{°}}{R}$.Since reaction is
exothermic, therefore $∆{H}^{°}$ itself will be negative resulting in positive slope.
