The heat change at constant volume for the decomposition of silver(I) oxide is found to be 30.66 kJ. The heat change at constant pressure will be

(a) 30.66 kJ
(b) > 30.66 kJ
(c) < 30.66 kJ
(d) unpredictable

Answer: > 30.66 kJ
Heat change at constant volume for the decomposition of silver(I) oxide = 30.66 kJ.
$Ag_2O(s) \longrightarrow 2Ag(s) + \frac{1}{2} O_2(g)$
Here, $\Delta n_g = +ve$
Thus, $\Delta H > \Delta E$
Since, $\Delta E = 30.66 kJ$, $\Delta H > 30.66 kJ.$
