Sulfur dioxide is produced in enormous amounts for sulfuric acid production. it melts at - 73˚c and boils at - 10˚c. its δh˚fus is 8.619 kj/mol and its δh˚vap is 25.73 kj/mol. the specific heat capacities of the liquid and the gas are 0.995 j/g·k and 0.622 j/g·k, respectively. how much heat is required to convert 2.500 kg of solid so₂ at the melting point to a gas at 60˚c?

Heat required to convert 2.500 kg of solid SO₂ at the melting point to a gas at 60˚C is 1,589.724 kilo joules.

Explanation:

Heat required to melt sulfur dioxide solid -73˚C =

Latent heat melting of sulfur dioxide =

Mass of sulfur dioxide solid , m= 2.500 kg = 2500 g

Moles of sulfur dioxide solid ,n=

Heat required to raise the temperature of liquid sulfur dioxide from -73˚C to -10˚C =

-10˚C = 263.15 K,  -73˚C = 200.15 K

Mass of sulfur dioxide liquid, m= 2.500 kg = 2500 g

Specific heat of liquid sulfur dioxide =

Change in temperature =

Heat required to vaporize sulfur dioxide liquid at -10˚C=

Latent heat melting of sulfur dioxide =

Mass of sulfur dioxide liquid, m= 2.500 kg = 2500 g

Moles of sulfur dioxide solid ,n=

Heat required to raise the temperature of liquid sulfur dioxide from -10˚C to 60˚C =

-10˚C = 263.15 K,  60˚C = 333.15 K

Mass of sulfur dioxide liquid, m= 2.500 kg = 2500 g

Specific heat of gas sulfur dioxide =

Change in temperature =

Heat required to convert 2.500 kg of solid SO₂ at the melting point to a gas at 60˚C = Q
