Constant volume calorimeters are usually calibrated using the combustion of benzoic acid, C6H5COOH(s). A couple of years ago in chem 327, a group of students calibrated the calorimeter in our lab using 1.0308 g of benzoic acid and, after combustion in the 'bomb', found a calorimeter temperature increase of 2.71 degrees. What is the calorimeter constant for this apparatus?

Transcribed Image Text:Constant volume calorimeters are usually calibrated using the combustion of benzoic acid, C₆H₅COOH(s). A couple of years ago in Chem 327, a group of students calibrated the calorimeter in our lab using 1.0308 g of benzoic acid and, after combustion in the 'bomb,' found a calorimeter temperature increase of 2.71 degrees. What is the calorimeter constant for this apparatus?
Expert Solution

Step 1
First we have to calculate the heat released by combustion of given mass of benzoic acid using its molar enthalpy of combustion.
Then using the given temperature change and heat, we can calculate calorimeter constant.
