Document Summary
Reaction rate is the number (mol) of chemical reactions occuring in the system per reaction volume (l) per time (s) Reaction rate is usually measured in mol/(lxs) A b : reaction rate is the number of mol/(lxs) of a converted into b every second. Rate = - [a]/ t change in concentration of a over time period t. Rate = [b]/ t change in concentration of b over time period t. Because [a] decreases with time, [a] is negative. Average rate: ([a] final - [a] initial ) / (t final - t initial ) Example: concentration of o 2 decreased from 0. 0150 m to 0. 0140 m in 3 minutes. Average rate: [o2]/ t= [o2] final [o2] initial / t final - t initial. Reaction rate = moles of reactions per volume (l) per time (s) For each mole of the reactions occurred:
