For the reaction of one mole of zinc dust with one mole of sulphur acid in a bomb calorimeter, `DeltaU and w` correspond to-

A

`DeltaU lt 0,w=0`

B

`DeltaU lt0,wlt0`

C

`DeltaU gt0,w=0`

D

`DeltaU gt0,wgt0`

Text Solution

Verified by Experts

The correct Answer is:
A
Bomb calorimeter is commonly used to find the heat of combustion of organic substances which consists of a sealed combustion chamber, called a bomb. If a process is compression is allowed, so `w=0 and DeltaU=q`.
`DeltaU lt 0, w=0`.
