Parts and what they mean

• Distribution at temperature t (ताप t पर वितरण) — Taller, narrower peak at lower energy.
• Distribution at (t + 10) ((t + 10) पर वितरण) — Peak moves to higher energy and the curve broadens; the total area stays the same (total probability = 1).
• Activation energy Ea (सक्रियण ऊर्जा Ea) — Only molecules to the right of this line can react on collision.
• Shaded area at t: fraction with E ≥ Ea (t पर छायांकित क्षेत्र: E ≥ Ea वाला अंश) — This fraction is e^(−Ea/RT) in the Arrhenius equation.
• Extra area at (t + 10) ((t + 10) पर अतिरिक्त क्षेत्र) — The area beyond Ea roughly doubles for a 10° rise, so the rate roughly doubles (curves exaggerated for clarity).
• Fraction of molecules vs kinetic energy (अणुओं का अंश बनाम गतिज ऊर्जा) — NCERT Fig 3.9.
