Question

The value of $\Delta G^{\circ }$ for the phosphorylation of glucose in glycolysis is 13.8 kJ/mol. Find the value of $K_c$ at 298 K.

• A. $5.8\times {10}^{-5}$
• B. $5.8\times {10}^5$
• C. $3.8\times {10}^3$
• D. $3.8\times {10}^{-3}$

Answer 1

The correct option is D $3.8\times {10}^{-3}$

$\Delta G^{\circ }=-RTln{K}_c$

Substituting the values, we get

$13800=-8.314\times 298\times ln{K}_c$

$\therefore K_c=3.8\times {10}^{-3}$
