What’s on the Reaction Rates poster
A 5-row table: Factor · Increases rate by.
Factor and mechanism.
- Concentration — More frequent collisions
- Pressure (gases) — More frequent collisions
- Surface area — More exposed particles
- Temperature — More energy AND more frequent collisions
- Catalyst — Lower activation energy pathway
Temperature works mainly by increasing the proportion of molecules above the activation energy, not by speeding collisions.
Questions about the Reaction Rates poster
- What’s on the Reaction Rates poster?
- A 5-row table: Factor · Increases rate by. Factor and mechanism. Concentration — More frequent collisions; Pressure (gases) — More frequent collisions; Surface area — More exposed particles; Temperature — More energy AND more frequent collisions; Catalyst — Lower activation energy pathway. Temperature works mainly by increasing the proportion of molecules above the activation energy, not by speeding collisions.
- Who is the Reaction Rates poster for?
- Reaction Rates 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 Reaction Rates poster?
- All five factors work by changing collision frequency or collision energy. A wall chart earns its place by being glanceable from where the work is happening, so Reaction Rates belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Reaction Rates?
- Born-Haber Cycles, Equilibrium and Electrode Potentials sit alongside Reaction Rates 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 Reaction Rates poster free to download and print?
- Yes. Reaction Rates 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 Reaction Rates poster print at?
- Reaction Rates 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 Reaction Rates loses nothing.Printing guide
