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}.

What particles would you find in a nucleus of an atom
sammy [17]

Answer:

The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

Yuliya22 [10]

Answer:

2-chloro-1-methyl-cyclohex-1,4-diene.

Explanation:

Hello,

In this case, the addition of hydrochloric acid acts as an electrophilic atack in which the hydrogen bonded to the double-bonded carbon connected to the carbon with the methyl substitution is substituted by the chlorine from the hydrochloric acid, in such a way, 2-chloro-1-methyl-cyclohex-1,4-diene is produced as one equivalent of HCl is used therefore one substitution will be attained for chlorine, and hydrogen as a side product as shown on the attached picture.

Best regards.
