Rate Of Reaction

The Change in concentration of a reactant or product per unit of time

Order of reactant

The power to which the concentration of the reactant is raised in the rate equation

Rate Constant

K, is the constant that links the rate of reaction with the concentrations of the reactants raised to the owers of their orders in the rate equation

Half Life

The time taken for the concentration of the reactant to reduce by half

Rate Determining Step

The slowest step in the reaction mechanism of a multi-step reaction

Suggest mechanism of:

NO₂(g) + CO(g)--> NO(g) + CO₂(g)

Rate=k[NO₂(g)]²

NO₂ + NO₂ --> NO + NO₃

NO₃ + CO --> NO₂ + CO₂
