Find the two conditions for free energy: equilibrium and
resonance and find their form in the spherical coordinates. (This
question is about Effective internal field in a
ferromagnet. General expression for resonance field.)
(a) What is resonance and the conditions for resonance? Give
examples. (b) What is the Doppler effect, and how is it produced?
Cite two examples. (c) Why does a police siren sound different when
it’s approaching you and when it’s passed you? Explain what is
happening as thoroughly as possible. (d) What are the similarities
and differences between Coulomb's law and Newton's law of
gravitation?
What does it mean for a free energy diagram of an equilibrium
reaction when delta G is zero? Does that mean that the entire
diagram would just be a horizontal line, or would there still be
transition and intermediate states?
Exercise 18.67: Problems by Topic - Cell Potential, Free Energy,
and the Equilibrium Constant Calculate the equilibrium constant for
each of the reactions at 25 ∘C. Part A
Pb2+(aq)+Mg(s)→Pb(s)+Mg2+(aq) Express your answer using one
significant figure. K = ? Part B Br2(l)+2Cl−(aq)→2Br−(aq)+Cl2(g)
Express your answer using one significant figure. K = ? Part C
MnO2(s)+4H+(aq)+Cu(s)→Mn2+(aq)+2H2O(l)+Cu2+(aq) Express your answer
using one significant figure. K = ?
1. Find the standard form of the equation of the hyperbola
satisfying the given conditions. Foci at (-5,0) and (5,0); vertices
at (1,0) and (-1,0).
2. Find the standard form of the equation of the hyperbola
satisfying the given conditions. Foci at (0,-8) and (0,8); vertices
at (0,2) and (0,-2).
Using standard reduction potentials, calculate the standard emf,
free energy, and equilibrium constant at 298K for each of the
following reactions:
a. Cl2(g) + 2 I-(aq) → 2 Cl-(aq) + I2(s)
b. 2 NO3-(aq) + 8 H+(aq) 3 Cu(s) → 2 NO(g) + 4 H2O(l) + 3
Cu2+(aq)
c. Fe(s) + 2 Fe3+(aq) → 3 Fe2+(aq)
