approximation of g formalized as the delta method: Theorem 17 3 (Delta method) If a function g: R !R is di erentiable at 0 with g0( 0) 6= 0 and if p n( ^ 0) !N(0;v( 0)) in distribution as n!1for some variance v( 0) then p n(g( ^) 0g( 0)) !N(0;(g( 0))2v( 0)) in distribution as n!1 Proof sketch We perform a Taylor expansion of g( ^) around

What is Delta text G G?

We can use the sign of Delta ext G ?G to figure out whether a reaction is spontaneous in the forward direction, backward direction, or if the reaction is at equilibrium. , the process is exergonic and will proceed spontaneously in the forward direction to form more products.

What is the difference between ?G and ?rG?

Since ?G is a difference between two values of G, it has to have units of kJ. On the other hand, ?rG is a gradient and therefore has units of kJ / mol. Unfortunately, the notation ?G is often loosely used and treated as being synonymous with ?rG. You will therefore see people give ?G units of kJ mol ? 1.

What does g 0 mean?

The sign of ?G indicates the direction of a chemical reaction and determine if a reaction is spontaneous or not. ?G < 0: reaction is spontaneous in the direction written (i.e., the reaciton is exergonic) ?G = 0: the system is at equilibrium and there is no net change either in forward or reverse direction.

What is the relationship between ?G and gproducts - greactants?

Since ?G is the difference between the Gibbs free energy of one state and another, ?G has to have the same units as G, which is units of energy. Now, this does not necessarily mean that ?G = Gproducts ? Greactants. For example, if I changed my question to be:
