what is the purpose of measuring conductivity and temperature in determining a reaction type?

Answer #1

Conductivity changes as a product increases or reactant decreases, so we can follow the concentration or extent of reaction if we measure conductivity. This is typically for Titrations (i.e. the molecular HA will form ionic H+ and A- in solution, which make conduciton possible)

The temperature is helpful for those reaciton which are either endothermic or exothermic.

As T increases, if this is exothermic, we can assure the reaction is proceeding in the forward direction

If T decreases, and this is endothermic, the reaction is also going in the forward direction

Therefore, both are excellent types of variables which let us know the type of reaction and extent of reaction

Measuring the electrical conductivity of a solution. Ammonia solution is added from a burette to 50.0 cm3 of hydrochloric acid in a beaker. When the NH3 is added to the solution, the conductivity decreases until 20 cm3 of NH3 is added. The ammonia solution has a density of 0.075 g cm-3 and contains 40% by mass of ammonia. Find the molarity of the hydrochloric acid.

To determine the effect of the temperature dependence of the thermal conductivity on the temperature distribution in a solid, consider a material for which this dependence may be represented by: k = k0 + a T, where “k0“ is a positive constant and “a” is a coefficient that may be positive or negative. Starting with a steady-state energy balance, derive a relationship for temperature (T) as a function of distance (x) from the lower temperature wall. You may assume that...

Experimental investigation determining the thermal conductivity for three different materials, silver painted zincalume, acrylic and black timber. Expected that zincalume would have the highest conductivity followed by acrylic and then timber (best insulator). Results found the opposites where timber had the highest conductivity (k= 0.317) then acrylic (k=0.307) and zincalume (k=0.303) How do I scientifically explain these results using the theory of heat transfer?
