The reason for the slight increase in the first ionization energies of manganese, iron, and cobalt but the considerable increase in gallium, germanium, and arsenic has to be determined. Concept Introduction: The energy that is needed to remove an electron from the isolated, neutral gaseous atom is known as ionization energy. It is represented by I . The energy required to remove the first electron from the neutral atom is called the first ionization energy, denoted by I 1 . The energy required to remove the second electron from the monovalent anion is called the second ionization energy, denoted by I 2 and so on. Energy is always supplied to the atom so as to remove an electron from it so ionization energies have positive values.

Given a system with an anodic overpotential, the variation of η as a function of current density- at low fields is linear.- at higher fields, it follows Tafel's law.Calculate the range of current densities for which the overpotential has the same value when calculated for both cases (the maximum relative difference will be 5%, compared to the behavior for higher fields).

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: N2 (g) + 3H2 (g) = 2NH3 (g) AGº = -34. KJ Now suppose a reaction vessel is filled with 8.06 atm of nitrogen (N2) and 2.58 atm of ammonia (NH3) at 106. °C. Answer the following questions about this system: rise Under these conditions, will the pressure of N2 tend to rise or fall? ☐ x10 fall Is it possible to reverse this tendency by adding H₂? In other words, if you said the pressure of N2 will tend to rise, can that be changed to a tendency to fall by adding H2? Similarly, if you said the pressure of N will tend to fall, can that be changed to a tendency to rise by adding H₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of H₂ needed to reverse it. Round your answer to 2 significant digits. yes no ☐ atm Х ด ? olo 18 Ar
