Question
Which of the following is not a valid assumption of calorimetry?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Calorimetry experiments measure heat changes. Assumptions often include perfect insulation (no heat loss) and that the calorimeter itself doesn't absorb heat. The specific heat of water is a known constant. However, reactions do not need to go to completion; calorimetry measures the heat for the extent of reaction that occurs.
Hint
Calorimetry measures the heat released or absorbed for the actual reaction that takes place, not necessarily for a complete reaction.
