Question

Calculate the amount of heat (in kJ) released when 35.0 g of benzene vapor is cooled from 96.0ºC to 26.4ºC. For benzene:

b. p. = 80.09ºC, ΔH_vap = 30.72 kJ/mol

m. p. = 5.49ºC, ΔH_fus = 9.87 kJ/mol

C_{p, liq} = 136.0 J/(mol ºC)

C_{p, vap} = 82.4 J/(mol ºC)

Accepted Answer

–17.6 kJ

Answer

–12.4 kJ

Answer

–9.91 kJ

Answer

–5.32 kJ
