The Zero-Order Integrated Rate Law
Captions available
The idea
For a zero-order reaction, concentration falls linearly with time at a constant rate, independent of how much reactant remains.
In practice
Ammonia decomposing on tungsten gives a straight-line plot of concentration against time, unlike its curved plot on quartz.
Where people slip
A constant rate does not mean an unlimited one — a zero-order reaction still stops once its reactant is consumed.
