Concept explainers
(a)
Interpretation: The temperature and pressure where all the three solid phases of Thallium metal present and the melting point of Thallium increase or decrease with increasing pressure is to be stated.
Concept introduction: Phase diagrams are the equilibrium diagrams that show the phases and how these phases are affecting due to the changes in temperature, pressure and composition of an alloy.
There are three different lattices or structures, body-centered cubic (bcc), face-centered cubic (fcc) and hexagonal close-packed (hcp). Eutectic point is the point at which temperature is the lowest and the point of intersection is between the liquid and solid.
To determine: The temperature and pressure where all the three solid phases of Thallium metal present.
(b)
To determine: The melting point of Thallium increase or decrease with increasing pressure.

EBK CHEMISTRY: THE SCIENCE IN CONTEXT,
- The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1arrow_forwardDon't used Ai solutionarrow_forwardIn an experiment, the viscosity of water was measured at different temperatures and the table was constructed from the data obtained. a) Calculate the activation energy of viscous flow (kJ/mol). b) Calculate the viscosity at 30°C.

If the cavity is 12 cm long, how many modes oscillate in the cavity? How long does it take for the radiation to travel the entire cavity? What is the frequency difference between 2 consecutive modes?(refractive index of the medium n = 1).arrow_forward

What is the frequency difference between 2 consecutive modes?(refractive index of the medium n = 1).arrow_forwardThe number of microstates corresponding to each macrostate is given by N. The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?arrow_forwardFor the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forward
