Half Life
time taken for a variable to fall to half its original value
1 of 14
Rate Determining Step
the slowest step and determines the overall rate
2 of 14
Order of Reaction
power to which a conc. is raised in the rate equation
3 of 14
Activation Energy
minimum amount of energy particles need to have if a collision between them is to result in a reaction
4 of 14
Kinetics
the study of rates of reactions and factors affecting rates
5 of 14
First Order
rate of reaction is directly proportional to the concentration
6 of 14
Colorimetry
measures the conc. of a coloured solution by measuring the amount of a specific wavelength of light absorbed by the solution
7 of 14
Catalyst
a substance that speeds up a chemical reaction without going through any chemical change
8 of 14
Zero Order
rate of reaction is independant of the concentration of the species
9 of 14
Second Order
rate of reaction is proportional to the concentration of that species squared.
10 of 14
Overall Order
sum of the powers to which the concentrations have been raised
11 of 14
Rate Equation
an equation that relates conc. of substances to the rate of reaction
12 of 14
Rate of Reaction
rate at which reactants are consumed or products are formed in a reaction
13 of 14
Rate Constant
constant of proportionality in the rate equation, given by symbol "k"
