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

Options:

Answer:

Solution:

Bomb calorimeter commonly used to find the heat of combustion of organic substances, consists of a sealed combustion chamber, called a bomb. The reaction in a bomb calorimeter proceeds at constant volume so, $w = 0$ and $Δ U = q$ . Hence, $Δ U < 0, w = 0$ .
