A2 - Kinetics

Rate Equations and Determination of the Rate equation.

Define Rate of Reaction: The change in concentration of products or reactants over a unit of time.
Define Rate Constant: The constant of proportionality in a rate expression.
How can the order of reaction for a product be determined? By experimentation only.
How is the rate of a reaction altered by a product with Zero order? Unaffected.
How is the rate of a reaction altered by the concentration of a product with First order? As the concentration is doubled, the rate is doubled .
How is the rate of reaction altered by the concentration of a product with Second Order? As the concentration is altered the rate is raised to the power of this alteration, eg. as it is doubled (x2) the rate will be (2squared = x4).
How does temp affect rate constant? It increases it.
What is the total order of a reaction? The sum of the powers of the concentrations in a rate equation
