Explanation of Solution
The reaction is given below.
The first set of equilibrium partial pressures are
By substituting these values in the above expression, the value of equilibrium constant can be calculated.
The pressure of
According to Le Chatelier’s principle, the position of the equilibrium will shift towards right in response to the addition of
To determine the new equilibrium conditions, a pressure table can be set up as given below.
Substitute the equilibrium pressures into the equilibrium – constant expression as shown below.
The value
Then,
The total pressure after equilibrium is re-established can be calculated as given below.
As a final check, it can be shown that,

- The molar absorptivity of a protein in water at 280 nm can be estimated within ~5-10% from its content of the amino acids tyrosine and tryptophan and from the number of disulfide linkages (R-S-S-R) between cysteine residues: Ε280 nm (M-1 cm-1) ≈ 5500 nTrp + 1490 nTyr + 125 nS-S where nTrp is the number of tryptophans, nTyr is the number of tyrosines, and nS-S is the number of disulfide linkages. The protein human serum transferrin has 678 amino acids including 8 tryptophans, 26 tyrosines, and 19 disulfide linkages. The molecular mass of the most dominant for is 79550. Predict the molar absorptivity of transferrin. Predict the absorbance of a solution that’s 1.000 g/L transferrin in a 1.000-cm-pathlength cuvet.
