Free energy, ΔG, is the energy free to do work. When ΔG<0, then the system can do work and the magnitude of△G is the maximum amount of work the system could do. When ΔG>0, the work is done to thesystem and ΔG is the minimum amount of work that needs to be done. Consider the calcium ion moving up the concentration gradient. This is not spontaneous. What is AG for the reaction assuming it occurs at 37ºC.
Ca²⁺ (aq, 10⁻⁵M) ↔ Ca²⁺ (aq, 10⁻³ M)
AG= ____ k.J
Which statement is accurate:
a. This is the minimum amount of work done by the system
b. This is the minimum amount of work that needs to be done to the system to make the calcium go up the gradient.
c. This is the maximum amount of work that the system can do
d. This is the maximum amount of work that needs to be done to the system to make the calcium go up the gradient.
