1)

 A plot In K against $\frac {1}{T}$ (abscissa) is expected to be a straight line with intercept  on ordinate axis equal to 


A) $\frac{\triangle S^{0}}{2.303 R}$

B) $\frac{\triangle S^{0}}{ R}$

C) -$\frac{\triangle S^{0}}{ R}$

D) $\triangle S^{0}\times R$

Answer:

Option B

Explanation:

$RT In K =-\triangle G^{0}=T\triangle S^{0}-\triangle H^{0}$;

 $ In K =\frac{\triangle S^{0}}{R}-\frac{\triangle H^{0}}{RT}$

 Thus, a plot of  In  K versus 1/T (abscissa)  will be straight line with slope equal to

 $\frac{-\triangle H^{0}}{R}$ and intercept $\frac{\triangle S^{0}}{R}$
