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

A

`DeltaU lt 0, w=0`

B

`DeltaU=0, wlt0`

C

`DeltaUgt0, w=0`

D

`DeltaUlt0, 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 scaled combustion chamber, called a bomb. If a process is run in a sealed container then no expansion or compression is allowed, so w = 0 and `DeltaU = q`.
`DeltaUlt0, w=0`
