What’s on the Rate Equations poster
The rule, 3 worked examples, and the mistake everyone makes.
- The rate equation relates rate to reactant concentrations raised to their orders.
- rate = k[A]^m[B]^n
- Zero order in A = Doubling [A] does not change rate
- First order in A = Doubling [A] doubles the rate
- Second order in A = Doubling [A] quadruples it
- Common mistake: Taking orders from the stoichiometry → Determining them from rate data
Overall order is the sum of the individual orders. The rate-determining step contains the species that appear in the rate equation.

- Who is the Rate Equations poster for?
- Rate Equations belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning physical chemistry can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Rate Equations poster?
- Orders are found experimentally. They cannot be read from the balanced equation. A wall chart earns its place by being glanceable from where the work is happening, so Rate Equations belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Rate Equations?
- Born-Haber Cycles, Equilibrium and Electrode Potentials sit alongside Rate Equations in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Born-Haber CyclesEquilibriumElectrode Potentials
- Is the Rate Equations poster free to download and print?
- Yes. Rate Equations downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Rate Equations poster print at?
- Rate Equations is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Rate Equations loses nothing.Printing guide
