Question

For a reaction of conversion of ATP into ADP at 20⁰C, calculate the reaction Gibbs free energy. Given the change in enthalpy is 20.27 Kcal and the change in entropy is 85 cal/Kelvin

Answer 1

To be given in question

T=273+30=293K

∆H=20.27Kcal

∆S=85cal/K

We know that

$∆G=∆H-T∆S$

Put value

$$∆G=20270-293\times85=20270-24905=-4635Cal$$

$∆G=-4.635Kcal$
