The heat of combustion of ethanol determined in a bomb calorimeter is - 670.48kilo calori per mole at 27 degree Celsius what is ∆H at 27 degree Celsius for the reaction?
Most Upvoted Answer
The heat of combustion of ethanol determined in a bomb calorimeter is ...
Calculation of ∆H for the reaction:
Given data:
- Heat of combustion of ethanol in a bomb calorimeter = -670.48 kcal/mol
- Temperature = 27°C
Step 1: Convert temperature to Kelvin
- Temperature in Kelvin = 27 + 273 = 300 K
Step 2: Calculate ∆H for the reaction
- ∆H = -670.48 kcal/mol
- Since the heat of combustion is negative, it means the reaction is exothermic
- The heat of combustion is the heat released when one mole of a substance is burned completely in excess oxygen
- Therefore, the ∆H for the reaction is -670.48 kcal/mol
Conclusion:
- The ∆H for the reaction at 27°C is -670.48 kcal/mol
