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

Options

A. `DeltaUlt0,w=0`
B. `DeltaU=0,w=0`
C. `DeltaUgt0,w=0`
D. `DeltaUlt0,wgt0`

Answer

C

Explanation

Bomb calorimeter is commonly used to find the heat of combustion of organic substance which consists of a scaled combustion chamber, called a bomb. If a process is run in a scaled container then no expansion or compression is allowed, so `w=0` and `DeltaU=q` .
`DeltaUlt0,w=0`
