Interpretation:
The importance of physical state of reactants and products for equilibrium constants expression is to be explained.
Concept introduction:
The equilibrium constant is equals to the ratio of concentrations of products to that of reactants.
Answer to Problem 39A
The physical state of reactants and products are important for the equilibrium constant because for the heterogeneous reactions, the concentrations of pure solids are not included because their concentration is remains constant. So, the concentration of pure solids are not appear in the equilibrium constant expression
Explanation of Solution
The physical state of reactants and products are important for the equilibrium constant because for the heterogeneous reactions, the concentrations of pure solids are not included because their concentration is remains constant. So, the concentration of pure solids is not appearing in the equilibrium constant expression.
The concentration of pure solids and liquids are taken as unity and when the substance occurs in liquid solutions, their concentrations are variable and so, their concentration are given in equilibrium expression.
The physical state of reactants and products are important for the equilibrium constant because for the heterogeneous reactions, the concentrations of pure solids are not included because their concentration is remains constant. So, the concentration of pure solids are not appear in the equilibrium constant expression.

- Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…arrow_forwardNonearrow_forwardHow will you prepare the following buffers? 2.5 L of 1.5M buffer, pH = 10.5 from NH4Cl and NH3arrow_forward
