Q) The value of ^G* for the phosphorylation of glucose in glycolysis is 13.8kJ/mol . Find the value of Kc at 298K?

We know that,

ΔG° = -2.303 RT log Kc

Where R = 8.314 J K-1 mol-1 ; T = 298 K ; 

Given,

ΔG° = 13.8 kJ/ mol but as value of R is in Joules we take it as 13.8 x 103 j/mol

Therefore 13.8 x 103 = -2.303 x 8.314 x 298 log Kc

logKc = -2.4185

Taking Antilog 

Kc = 0.2621 x  10 -2
