The Rate Law and Reaction Order
Captions available
The idea
A rate law expresses a reaction's rate as its rate constant times each reactant's concentration raised to that reactant's reaction order.
In practice
rate = k[H2O2] states that hydrogen peroxide's decomposition is first order in hydrogen peroxide.
Where people slip
A reaction order is usually a small positive integer, but it can be a fraction, zero, or negative — nothing guarantees a whole number.
