General Chemistry problems
B - If you write the rate constant expressions correctly, you will see that the rate constant for reaction (2) is actually the inverse of rate constant of reaction (1). So you will get the answer when take 1 divide by 4.22 x 10-3.

10 Chemistry Problems on half-life and formation
A particular first-order reaction has a rate constant of 1.35x102s-1 at 25ºC. What is the magnitude of k at 95ºC if Ea=55.5 kJ/mol?

Weak Electrolyte undergoes Ionization
Therefore, at equilibrium:
k1[H2O] = k-1[H+][OH-]
Rearranging, we get:
k1/k-1 = [H+][OH-]/[H2O] = Kd
Kd is the new constant made up of the two rate constants. It is called the dissociation constant or the equilibrium constant.

Five Physical Chemistry Questions
10) The reaction of NO and O2 produces NO2
2NO(g) + O2(g) ---> 2 NO2(g)
The rate constant is second order with respect to NO(g) and first order with respect to O2(g). At a given temperature, the rate constant, k, equals 6.1E3 M-2S-1.
