What is the equation for rate of reaction?
Change in concentration/time
Is the rate of reaction always dependent on the concentration of all species in the reaction?
No - may only be dependent on the concentration of some of the species not always all of them
Explain what the term “order of reaction” means (with respect to a reactant)
Power of concentration term (in rate equation) i.e. magnitude of the contribution of each species to the rate of reaction
How would you know a reactant was zero order?
As the concentration changes, rate remains the same
How would you know a reactant was 1st order?
As the concentration changes by a factor, the rate changes by the same factor
How would you know a reaction was 2nd order?
As the concentration changes by a factor, the rate changes by that factor squared
What do you need to find in an experiment before any orders of reaction can be found?
• Initial known concentration 2. Initial rate of reaction. Experiment is then repeated at different initial concentrations and new initial rates measured
What does the rate-concentration graph look like for a zero order reactant?
