An interaction between 2 subunits of a protein was determined to have a ?G°'= -57.05 kJ/mol.What is the K?q for the reaction at 25°C? A)10-10 B)1.02 C)1.32 D)10¹⁰

Question

Quizplus · Accepted Answer

The relationship between ∆G°¢ and Kₑq is described by the equation ΔG°¢ = -RTlnKₑq, where R is the gas constant and T is the temperature in Kelvin.
R = 8.314 J/mol.K
Converting ∆G°¢ from kJ/mol to J/mol:
∆G°¢ = -57.05 kJ/mol × 1000 J/kJ/mol = -57,050 J/mol
Substituting the values in the equation:
-57,050 J/mol = -(8.314 J/mol.K × 298 K) lnKₑq
lnKₑq = 25.655
Taking the exponential of both sides:
Kₑq = e^25.655 = 1.02 × 10^11
Therefore, the answer is D: 1010.
