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

Answer»

`Delta U lt 0 , W =0`
`Delta U GT 0, w =0`
`Delta U lt 0, w lt 0`
`Delta U gt 0 , w gt 0`

Solution :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`.
