Colorful science illustration of an activation energy diagram, showing particles, a flame, and text explaining 'High activation energy = slow reaction ...until heated!'.

Image Concept: High Activation Energy = Slow Reaction Unless Heated Composition Central Hill Barrier A colorful, exaggerated “energy hill” labeled “Activation Energy” at the peak in neon pink. Particle Crowd On the left side: dozens of small circles in muted blue, representing particles lacking energy. On the right side: only a few bright yellow circles that have crossed the hill. Heat Source A stylized flame or red-orange thermometer at the bottom right, with glowing heat waves rising toward the particles. Text Overlay Positioned at the top: “High activation energy = slow reaction” Positioned near the heat source: “until heated!” Use a random bright color—like lime green—for the text so it pops against the background. Color Scheme Background: Deep purple gradient to make elements stand out Barrier: Neon pink Particles: Muted blue (inactive), bright yellow (energized) Heat: Fiery red-orange Text: Lime green This bold, high-contrast illustration will cement the idea that without adding heat, most particles can’t surmount the activation energy barrier, making the reaction slow.
