The denaturation of a biological macromolecule can be described by the equilibrium: macromolecule in native form ⟷ macromolecules in denatured form a. Show that the fraction theta of denatured macromolecules is related to the equilibrium constant Kd for the denaturation process by theta= Kd / (1 + Kd)

The denaturation of proteins can be described by the equilibrium F⇌U where F and U represent the folded and unfolded proteins, respectively. For lysozyme, ΔuH0′298K= 335kJ/mol and ΔuS0′298K= 980J/K.mol. The subscript 'u' refers to 'unfolding'. A) Calculate the equilibrium constant for the equilibrium F⇌Uat 298K B) Suppose you dissolve a certain amount of lysozyme in aqueous buffer at 298K. What fraction of the lysozyme protein molecules will be unfolded once equilibrium is reached? The fraction of unfolded lysozyme is the...

For the reaction A(aq) + BB(1) - C(s) + (aq) the equilibrium constant, K, can be written as PoD K- A When calculating the equilibrium constant, aqueous solutes must be expressed in moles per liter (M), and gases must be expressed in pressure as bars. This is because they are dimensionless ratios of the actual concentration or pressure divided by standard state concentration, which is M for solutions and 1 bar for gases. these are the only units of concentration...

Which of the following statements about equilibrium expressions and equilibrium constants are correct? Choose all that apply. Check all that apply. For chemical reactions in which all reactants and products are gases, K. can never be equal to K The equilibrium expression for a reaction involving only gases can be written in terms of either partial pressures or concentrations. A homogeneous equilibrium is one where all reactants and products are in the same physical state, When a chemical reaction is...

The equilibrium constant for the following reaction
can be expressed by the empirical formula
in the interval 445 K < T < 460 K. Use this expression to
calculate ∆rH◦ and ∆rS ◦ at 450 K and derive
an equation for ∆fH◦ of Ag2O (s) in this
temperature range. Now use the following heat capacity data:
to calculate ∆rH◦ , ∆rS◦ , and
∆rG◦ at 298 K. Would Ag2O be automatically
decomposed when exposed to the atmosphere (the partial pressure...
