Question

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

Answer 1

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 run in a sealed container then no expansion or compression is allowed, so w = 0 and ∆U = q.

∆U < 0, w = 0

Answer 2

Answer:

The Bomb calorimeter can be commonly used to calculate the heat of the combustion of various organic substances. It consists of a combustion chamber with seal named as the bomb. If any process can run in any sealed container, no compression or expansion is then allowed. Hence, w = 0 and ∆U = q. ∆U < 0, w = 0.
