In a bomb calorimeter the combustion of 0.5 g of compound A(molar mass...
Given data:
- Mass of compound A: 0.5 g
- Molar mass of compound A: 50 g/mol
- Temperature increase: 4 K
- Heat capacity of the calorimeter and material: 2.5 kJ/K
Calculating moles of compound A:
To calculate the molar internal energy of combustion, we first need to determine the number of moles of compound A. We can use the formula:
Number of moles = Mass / Molar mass
Number of moles = 0.5 g / 50 g/mol = 0.01 mol
Calculating heat transferred:
The heat transferred during the combustion can be calculated using the formula:
Heat transferred = Heat capacity × Temperature change
Heat transferred = 2.5 kJ/K × 4 K = 10 kJ
Calculating the molar internal energy of combustion:
The molar internal energy of combustion can be calculated using the formula:
Molar internal energy of combustion = Heat transferred / Number of moles
Molar internal energy of combustion = 10 kJ / 0.01 mol = 1000 kJ/mol
Therefore, the molar internal energy of combustion of compound A is 1000 kJ/mol.
Explanation:
- The molar internal energy of combustion is a measure of the energy released when one mole of a compound undergoes complete combustion.
- In this case, we are given the mass of compound A and its molar mass, which allows us to calculate the number of moles.
- The temperature increase in the bomb calorimeter is a result of the combustion reaction, and the heat capacity of the calorimeter and material is given.
- Using the heat capacity and the temperature change, we can calculate the heat transferred during the combustion reaction.
- Finally, we divide the heat transferred by the number of moles to obtain the molar internal energy of combustion.
- The molar internal energy of combustion is expressed in kJ/mol, which represents the energy released per mole of compound combusted.
- Mass of compound A: 0.5 g
- Molar mass of compound A: 50 g/mol
- Temperature increase: 4 K
- Heat capacity of the calorimeter and material: 2.5 kJ/K
