A solution contains 4.08 g of chloroform (CHCl3) and 9.29 g of acetone (CH3COCH3). The vapor pressures at 35 ∘C of pure chloroform and pure acetone are 295 torr and 332 torr, respectively.
Assuming ideal behavior, calculate the vapor pressures of each of the components and the total vapor pressure above the solution.
I calculated this out and got a vapor pressure of 325 torr; is this right? Why or why not? Can you tell me why and how the vapor pressure is affected by the increase in moles per solution.

A CMFR will be used to reduce the concentration of
chloroform(CHCl3) in water. Chloroform is a disinfection by-product
that is formed when chlorine is used to disinfect water; it is a
concern because it can cause cancer.The influent water contains 60
ppb chloroform and the Wisconsin State standard is 6 ppb.
Chloroform decays in the reactor at a rate of 0.2 hr-1
and the water flow rate is 100 L/day.
Treating the water to meet the Wisconsin standard will reduce...

Chloroform, CHCl3, is formed by the following reaction:
CH4(g) + 3 Cl2(g) → 3 HCl(g) + CHCl3 (g)
Determine the enthalpy change for this reaction (ΔH°rxn), using
the following:
enthalpy of formation of CHCl3 (g), ΔH°f = – 103.1 kJ/mol
CH4(g)
+ 2 O2(g) → 2 H2O(l) +

The iodination of acetone, CH3COCH3, in aqueous solution is
catalyzed by the hydrogen ion H+:
I2+CH3COCH3H+⟶HI+CH3COCH2I
The reaction can be followed visually by adding starch. The
purple starch-iodine complex forms immediately, then disappears
when the iodine has been consumed. The kinetics of the reaction may
be determined by recording the time required for the color to
disappear, which is the time required for the iodine, I2, to be
consumed.
