Document Summary

Factors that affect the rate of chemical reactions: Units of reaction rate: mol/(l*s) = m/s. Definition: an equation expressing the instantaneous reaction rate in terms of concentrations, at any instant, Units of k of the substances taking: the rate law for determined and cannot be chemical equation for the reaction. *overall order: sum of the powers of m+n+ part in the reaction. a reaction is inferred from the. Rate constant (k: definition: constant of proportionality in a rate law, factors that affects the rate constant, the units of the rate constant vary depending on the overall order. Example: consider the units of k when the concentration is expressed in mol/l and the rate is expressed as mol*l-1*s-1. Example: for the reaction 2no + o2 2no2, initial rate data are: 0. 0050: write the complete rate law for the reaction. Definition: gives the concentration of reactants or products at any time after the start of the reaction.
