Which of the following symbols represent heat of reaction at constant volume?

Options

  1. AH
  2. Bdq
  3. CS
  4. DU

Correct answer

D. U

Step-by-step solution

According to the first law of thermodynamics, U = Q + W = Q - P _ ext V ( W =- P _ ext V ) For an isochoric process: V =0 Heat of reaction = q _ v = U
