The next 3 questions will walk you through using the Henderson-Hasselbalch equation for the following question. For each step pr

ovide a numerical answer. A solution is made by combining 300mL of 0.020M trimethyl amine, that is (CH3)3N and a 500mL of a 0.03M solution of it's conjugate acid, that is (CH3)3NH . The Kb for trimethyl amine is 6.3x10-5. The Henderson-Hasselbalch equation uses pKa not Kb, Calculate the pKa....

Response:

The pKa value is 13.0.

Clarification:

pKa + pKb = 14

For trimethylamine, Kb = 6.3 × 10^{-5}

Calculating pKb: pKb = - log (6.3 × 10^{-5})

= 1.0

Thus, pKa = 14 - pKb = 14 - 1.0

pKa = 13.0

Verification: The typical range for pKa in weak acids is from 2 to 13.

In the first step of glycolysis, the given two reactions are coupled. reaction 1:reaction 2:glucose+Pi⟶glucose-6-phosphate+H2OAT
lorasvet [2795]

Answer: Reaction 2 is a spontaneous one.

Explanation:

According to our understanding:

\Delta G= +ve, meaning the reaction is non-spontaneous

\Delta G= -ve, indicating the reaction is spontaneous

\Delta G= 0, stating that the reaction is at equilibrium

For a reaction to be classified as spontaneous, the Gibbs free energy must yield a negative value.

Reaction 1:

Glucose + Pi ⟶ glucose-6-phosphate + H₂O, ΔG = +13.8 kJ/mol\rightarrow

Reaction 2:

ATP + H₂O ⟶ ADP + Pi, ΔG = -30.5 kJ/mol\rightarrow

From this, we can conclude that ΔG being negative indicates that reaction 2 is indeed spontaneous.

1. Use the following thermochemical equation.
KiRa [2933]

Answer:

There's a lot to address, so I'm uncertain if I can tackle this; it feels overwhelming. Perhaps you could simplify it for me as it's quite extensive.

Explanation:

  • I wish I had the answers.
  • It's too complex.
  • This chemistry isn't familiar to me.
  • If you have another chemistry-related question, feel free to ask.
  • This is just too difficult.
