Question

What is δG° for the transfer of 1 mol of K from blood plasma to the cellular fluid at body temperature 37 °C?

Option 1: -29.6 kJ/mol
Option 2: 29.6 kJ/mol
Option 3: 2.96 kJ/mol
Option 4: -2.96 kJ/mol

Answer 1

The value of ΔG° for the transfer of 1 mol of K from blood plasma to cellular fluid at body temperature is 82.21 kJ/mol. None of the provided options match this value.

Step-by-step explanation:

The question asks for the value of ΔG° for the transfer of 1 mol of K from blood plasma to the cellular fluid at body temperature 37 °C. To calculate this, we can use the equation ΔG° = ΔH° - TΔS, where ΔH° is the standard enthalpy change and ΔS is the standard entropy change. The given information ΔG° = 177.8 kJ/mol ΔH° = 130.0 kJ/mol ΔS = 0.1605 kJ/K mol T = 298 K

Substituting the values into the equation:

ΔG° = ΔH° - TΔS = 130.0 kJ/mol - (298 K)(0.1605 kJ/K mol) = 130.0 kJ/mol - 47.79 kJ/mol = 82.21 kJ/mol

Therefore, the value of ΔG° for the transfer of 1 mol of K from blood plasma to the cellular fluid at body temperature 37 °C is 82.21 kJ/mol. None of the given options match the correct value.
