2 What is the equation for the overall reaction? A. NH2Cl + NH3 + OCl- + OH- --> N2H4 + 2H2O B. NH3 + 2OCl- --> N2H5+ + H2O + OH- + 2ClC. 2NH3 + OCl- --> N2H4 + 2H2O + ClD. NH3 + OCl- + OH- --> N2H4 + H2O + ClE. 2NH3 + OCl- --> N2H4 + H2O + Cl...
3 For this proven reaction mechanism, what will be the rate equation?
Fast, Equilibrium Slow NO2Cl NO2 + Cl NO2Cl + Cl NO2 + Cl2 A. A Rate = k'[NO2Cl] k [NO B. Rate = k'[NO2Cl][Cl] C. Rate = k'[NO2]2[Cl] D. Rate = k'[NO2Cl]2/ [NO2] E. Rate = k'[NO2Cl] 2 ... 4 What is the expression for the reaction quotient for this reaction?
H2CO3(aq) + H2O(l) HCO3-(aq) + H3O+(aq) A. Q= [H2CO3] [H2O] [HCO3-] [H3O+] B. Q= [H2CO3] [H2O] [HCO3-]
... C. Q= [HCO3-] [H3O+] [H2CO3][H2O] D. Q= [HCO3-] [H3O+] [H2CO3]

K comes from thermodynamics.
See Chapter 19, page 929 G G < 0: reaction is __________favored __________favored favored fav G > 0: reaction is ________ favored If K > 1, then G is negative If K < 1, then G is positive
