Enthalpy Review Questions Savita Pall

Mixing different concentrations or different chemicals: For a combination of two or more chemicals, you need to use a tabulated thermodynamic property called the relative apparent molar enthalpy if you are mixing one concentration of chemicals with some different concentration. You can find out information for most of the chemical combinations very easily. This tabulated data will provide you...
T hen we can calculate the enthalpy change by figuring out volume/pressure changes. [Assumed C v is constant]. We could use a constant pressure calorimeter (isobaric) to measure a temperature change and hence calculate the heat , q p , which gives us enthalpy change.

How To Calculate The Molar Enthalpy Change

Use information from the Data Book and the enthalpy change for the combustion of benzene, which was determined experimentally, to calculate the standard molar enthalpy of formation of benzene.

  • In order to calculate the molar heat of vaporization, you should write down the information that the problem provides. The problem will either provide two pressure and two temperature values, or the molar heat of sublimation, and the molar heat of fusion. The molar heat of sublimation is the energy needed to sublime one mole of a solid, and the molar heat of fusion is the energy needed to melt
  • to the right of the reaction equation. At constant pressure, heat flow equals enthalpy change: tells you the direction of heat flow, but what about the magnitude? The coefficients of a chemical reaction represent molar equivalents, so the value listed for the refers to the enthalpy change for one
  • 6/06/2012 · Determine the molar enthalpy for the reaction of magnesium with aqueous hydrochloric acid. ΔH for HCl = -162kJ/mol, and ΔH for MgCl2 (aq) = -801kJ/mol. I need to know where to start on this problem, like, how to calculate enthalpy/molar enthalpy, and how to use the ΔH's, please help, I have a final tomorrow, and my grade is hanging by a thread, thanks!
  • 15/07/2008 · Best Answer: a) For condensation, the change in enthalpy is calculated using the following equation: q = (no. of moles) * (delta H of vaporization) Since you are given moles, use the Hvap in molar units. The heat of vaporization of water is 40.65 kJ/mol Remember, you are not vaporizing. You are condensing a
