What electrical energy conversion takes place in a galvanic cell?

In a chemical reaction, your limiting reactant was used up. You have a large quantity of excess reactant remaining. Will the reaction procees? Why or why not?

Consider the one-electron species Na+10.
(a) Calculate the energy (in Joules) of the 3pz orbital of the Na+10 ion.
(b) Calculate the energy (in Joules) and wavelength (in nm) of the transition from the 5s orbital to the 3pz orbital of the Na+10 ion.
(c) Calculate the ionization energy of the Na+10 ion.

Interpret the bonding in carbon monoxide, CO. What would happen to the bond length if an electron were added or removed? Why?

The nu tilde of a C-H bond is typically 3000 cm^-1. Calculate the wave number (in cm ^-1) for the vibrational levels nu =0 and nu=1

The reaction rate of nitrogen monoxide and oxygen into nitrogen dioxide is given by the
expression
r = k [NO]2 [O2],
where r = reaction rate
k = reaction rate coefficient, which increases with increasing temperature.
a) What is the increase in the reaction rate when the concentration of nitrogen oxide is
doubled and the concentration of oxygen is tripled?
b) How much do you need to increase the nitrogen concentration to affect a nine-fold
increase in reaction rate, without changing other factors tha

Calculate the Stoichiometric air/fuel ratio for the complete combustion of Octane (CH8H18)

What is the difference between ΔG and delta ΔG˚/ΔG˚’ in thermodynamics? Looking at my textbook they both seem to mean the same thing - the change in free energy.

The equilibrium constant, K[sub]c[/sub], for the reaction:
C(s) + CO[sub]2[/sub] (g) = 2CO (g) is 0.113 at 1100 K.
What is the concentration of CO in a mixture at equilibrium if the CO[sub]2[/sub] concentration is 0.035 M?
