Question

In constant pressure calorimetry, what is the relationship between qᵣₓₙ and qₛₒₗₙ?
Options
A qᵣₓₙ = qₛₒₗₙ
B qᵣₓₙ = -qₛₒₗₙ
Correct Answer
C qᵣₓₙ = 2qₛₒₗₙ
D No relationship
Correct Answer

Option B is the correct answer.

Detailed Explanation

The magnitude of heat gained by solution equals the magnitude of heat lost by reaction, so qᵣₓₙ = -qₛₒₗₙ.

Hint

The notes state this relationship.
