Citrate synthase catalyzes the reaction: ????x????????o????c???????????????????? + ????c????????y???? − ????o???? → c???????????
Nady [450]

The given question is incomplete. The complete question is as follows.

Citrate synthase catalyzes the reaction

Oxaloacetate + acetyl-CoA \rightarrow citrate + HS-CoA

The standard free energy change for the reaction is -31.5 kJ*mol^-1

( a) Calculate the equilibrium constant for this reaction a 37degrees C

Explanation:

(a).  It is known that , relation between change in free energy (\Delta G) of a reaction and equilibrium constant (K) is as follows.

             \Delta G = -RT \times ln K  

where,  T = temperature in Kelvin

The given data is as follows.

         T = 310 K,       \Delta G = -31.5 kJ /mol = -31500 J/mol  (as 1 kJ = 1000 J)

Now, putting the given values into the above formula as follows.

     ln K = \frac{-(\Delta G)}{RT}

            = \frac{31500}{8.314 \times 310}

      ln K = 12.22

         K = antilog (12.22)

           = 2.1 \times 10^{5}

Therefore, we can conclude that value of equilibrium constant for the given reaction is 2.1 \times 10^{5}.

The state of matter that has molecules with the least random molecular arrangement:
Ksenya-84 [330]
Gas. Molecules in gas are able to move and vibrate around each other more freely than the molecules in liquids and/or solids due to the great amount of space in between them. Hope this helps! :)

gtnhenbr [62]

Answer:

  • Noble gases are <u>odorless, colorless,</u> and nonflammable gases that have low chemical <u>reactivity</u><u>.</u>
  • The full <u>valence electron shells</u><u> </u>of these atoms make noble gases extremely <u>stable</u><u>.</u>
  • & they are <u>unlikely to form chemical bonds</u><u> </u>because they have little tendency to gain or lose
