In a bomb calorimeter experiment, the chemical reaction takes place at constant volume. What is the value of work done (\( w \)) during such a process?

  1. \( -p_{\text{ext}}\Delta V \)
  2. \( \Delta U \)
  3. \( 0 \)
  4. \( q_v \)

Correct answer · Option 3

\( 0 \)

Explanation

Because the bomb calorimeter is a sealed rigid vessel, volume does not change (\( \Delta V = 0 \)), so no expansion work is done (\( w = 0 \)).
