Problem

Following data are given for the reaction :

\text{H}_2(g) + \frac{1}{2}\text{S}_2(g) \rightleftharpoons \text{H}_2\text{S}(g)


$T(\text{K})$	1023	1218	1362	1473	1667
$\log_{10} K_P$	2.025	1.305	0.902	0.643	0.257

Assuming

\Delta H^\circ

and

\Delta S^\circ

constant for the given range, calculate

\Delta H^\circ

for the reaction in the range

1000

to

1218 \text{ K}

. Calculate

\Delta G^\circ

and

\Delta S^\circ

at

1023 \text{ K}

.
