6. A student carries out a calorimetry experimentusing HCI and NaoH. What effect will each of the following have onthe calculated enthalpy of the reaction relative to the actualenthalpy of reaction? (larger, smaller or no change). Explain yourreasoning. a. The thermometer always registered a temperature 0.30oc higher than the actual temperature b. The calorimeter constantused in the calculations by the student is larger than the actualvalue. (Hint: The best way to answer this question is to take yourcalorimeter constant, add at least 5 or 10 to the value and quicklyredo the calculations. After completing the calculations, youshould be able to complete the following statement: As thecalorimeter constant increases, the calculated enthalpy of thereaction c. Unfortunately, the HCI concentration was actually 1.90M instead of the 2.00 M HCI used in the calculations. (Hint: do asimilar calculation. This is an estimate of how errors affect theresult. If your data is not matching the expected values, perhapsthese questions will help you understand why.)

Ans 6a No change While making calculation in calorimeter system the change in temperature that is increase in temperature of the calorimeter system is noted The change is temperature remains independent of an erroneously calibrated thermometer For example Assume actual initial temperature A 250C erroneous initial temperature B 2530C actual initial temperature C 270C See Answer
