Question

What can be concluded about the values of $\Delta H$ and $\Delta S$ from this graph ?

• A. $\Delta H>0,\Delta S>0$
• B. $\Delta H>0,\Delta S<0$
• C. $\Delta H<0,\Delta S>0$
• D. $\Delta H<0,\Delta S<0$

Answer 1

The correct option is A $\Delta H>0,\Delta S>0$

As we know,
$\Delta G=\Delta H-T\Delta S$
here,
as slope is negative so $-T\Delta S<0$
&
$T\Delta S>0$
$\Delta S>0$
Also as intercept is positive so
$\Delta H>0$
