Document Summary

Ectotherms: animals whose body temperature depends on their surroundings. Instantaneous rate: the rate of the reaction at any one point in time. Second order (n=2): the rate is proportional to the square of the concentration of a. Integrated rate law: a relationship between the concentrations of the reactants and time. Activation energy (ea): an energy barrier or hump that must be surmounted for the reactants to be transformed into products. Frequency factor (a): the number of times that the reactants approach the activation barrier per unit time. Activated complex (transition state): a high-energy intermediate state; must go through this to get from the reactant to the product. Collision model: a chemical reaction occurs after a sufficiently energetic collision between two reactant molecules. Orientation factor (p): a number, usually between 0 and 1, which represents the fraction of collisions with an orientation that allows the reaction to occur.
