When 1 mole Zn powder is reacted with 1 ...

When 1 mole Zn powder is reacted with 1 mole sulphuric acid in bomb calorimeter (closed isolated system),...........

A

`Delta U lt 0 , w =0`

B

`Delta U gt 0, w =0`

C

`Delta U lt 0, w lt 0`

D

`Delta U gt 0 , w gt 0`

Text Solution

Verified by Experts

The correct Answer is:
A
For the reaction in closed vessel, internal energy is `Delta U`.
Reaction is erothermic, therefore `Delta U lt 0`.
Volume of gas remains constant therefore work `w=0`.
