|
Give the integrated rate equations for zero, first and second order reactions. How can linear graphs be plotted for each. What do the slopes of each represent? Derive the half life equations for each.
|
Zero. [A]=[A]i - kt
First. [A]=[A] e^-kt Second 1/[A] - 1/[A]i = kt Zero. [A] vs, t. slope is -k First ln[A] vs. t . slope is -k Second 1/[A] vs. t. slope is k |

|
Give the rules for effusion rates. What is Graham's law?
|
Smaller atoms effuse faster. The law states that M1/M2 = root(2)/root(1)
|

|
What is the ground state energy of a hydrogen atom's electron?
What equation tells us the energy of any other of hydrogen's electron levels? How much energy is needed to pull an electron in the 3 energy level of hydrogen? |
-13.6eV
E = -13.6/n^2 E = -13.6/9......13.6/9 eV to take away the electron. |
|
|
What is Ionic strength? Give a sample calculation using BaCl2's dissociation at 1 molar.
|
It's the measure of the concentration of the ions in solution.
1M bacl2 goes to 1M Ba2+ and 2M Cl-. the calculation is .5 ((1M*2^2)+(2M*1^2)) = 3 |
|
|
What is the Arrenius Equation? How can we plot it where the slope of the graph can give us the activation energy? Derive this graph from the equation.
|
the equation is
k = A e^ (-Ea/RT) A graph of ln(k) vs. 1/T |
