Concept introduction:
The chemical equilibrium is a state of a chemical reaction when the rate of forward reaction becomes equal to the rate of reverse reaction and the concentration of the products and reactants becomes constant known as equilibrium concentrations.
According to Dalton’s law, the total pressure of the mixture of nonreactive gases is equal to the partial pressure of individual gases. The pressure utilized by the individual gas is called the partial pressure of that gas.
Equilibrium constant is the ratio of the concentration of reactants and products present in the chemical reaction.
For a general reaction:
The general formula for writing equilibrium expression for the reaction is given as:
Here,
A and B are reactants, C is products, and
For the general reaction:
The general formula for writing equilibrium expression for the reaction is given as:
Here,
A and B are reactants, C and D are products, and
Equilibrium constants of gas phase reaction are written in terms of partial pressures because concentration of gases is directly proportional to partial pressures.
The relationship between

Calculate the accurate monoisotopic mass (using all 1H, 12C, 14N, 160 and 35CI) for your product using the table in your lab manual. Don't include the Cl, since you should only have [M+H]*. Compare this to the value you see on the LC-MS printout. How much different are they? 2. There are four isotopic peaks for the [M+H]* ion at m/z 240, 241, 242 and 243. For one point of extra credit, explain what each of these is and why they are present. 3. There is a fragment ion at m/z 184. For one point of extra credit, identify this fragment and confirm by calculating the accurate monoisotopic mass. 4. The UV spectrum is also at the bottom of your printout. For one point of extra credit, look up the UV spectrum of bupropion on Google Images and compare to your spectrum. Do they match? Cite your source. 5.
