Answer to Question #309672 in General Chemistry for zed

Question

Acetone is essential as an industrial solvent and a starting reactant in the manufacturing of countless products, from films to synthetic fibers. At 20.2^oC, the vapor pressure of acetone is 24.50 kPa. If its Δ H_vap is 30.99 kJ/mol, what is the temperature (in ^oC) when the vapor pressure is 10.00 kPa?

Answer 1

$P1T2= P2T1$

24.5× T2= 20.2× 10

202/24.5

T2= 8.24°c
