Temperature Effects, Reaction Rate Theory, Catalysis
For most reactions as T increases, so does rate
Kinetic molecular theory can explain this
Arrhenius equation for temperature effects: k = Ae-E/RT ; A is an orientation factor; E is the activation energy
Do calculations of E and A from exptl. Data
Catalyst: accelerates rate without being consumed in reaction
Catalysts can be homogeneous e.g. acid in hydrolysis of esters; heterogeneous, solid metallic catalysts in reaction of nitrogen with hydrogen to make ammonia
Enzymes: common biochemical catalysts, e.g. in digestion
