DRAFT (Chap 10) Page 1 Chapter 10 –a closer look at ideas we’ve already briefly discussed.Thermodynamics–tells us IFa reaction will occur spontaneously, but not how fast. (Enthalpy and Entropy are thermodynamic properties.) Kinetics–kinetics tell us how fast the reaction will go (the rate of a chemical reaction or the speed at which it occurs). Equilibrium–most chemical reactions (and many physical processes) move to a state in which there exists a certain amount of reactants and a certain amount of products. When a system has reached the point where those amounts don’t change, the system is said to have reached equilibrium. A “System” is that portion of the universe that we single out for study. N2(g) + 3H2(g) 2NH3(g) 2NH3(g)N2(g) + 3H2(g) The above equations both show the same system, a system involved in the equilibrium of nitrogen gas and hydrogen gas with ammonia gas.
