Keq is only at equilibrium, Q is at any point in a reaction
If Q < Keq : rxn will go to products
If Q > Keq : rxn will go to reactants
The chemical standard states included that all gases are a 1 bar of pressure and 1 M concentration. The biochemistry standards include that solutes are at 1 M except H+ which would be at pH 7, and T at 310 K
-dG : spontaneous rxn goes to products and is favorable
+dG : nonspontaneous rxn goes to reactants
+dS (entropy) is favorable
-dH (enthalpy) is exothermic and favorable thermodynamically
Breaking bonds is endothermic
Building bonds is exothermic and favorable
K = e^-dG°'/[(R/1000)T]
Amide must have a nitrogen bonded to carbonyl
Amine can be bonded to H, alkyl groups, or aryl groups
