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

`30.66kJ`

B

` gt 30.66kJ`

C

` lt 30.66kJ`

D

Unpredictable

Text Solution

Verified by Experts

The correct Answer is:
B
`Ag_(2)O(s)to2Ag(s)+(1)/(2)O_(2)(g)`
Here `Deltan_(g)=+ve`
Thus `DeltaH gt DeltaE`
Since `DeltaE=30.66 kJ`
Thus `DeltaH gt 30.66 kJ`
