Parts and what they mean

• Concentration of butyl chloride vs time (ब्यूटिल क्लोराइड की सांद्रता बनाम समय) — C₄H₉Cl + H₂O → C₄H₉OH + HCl. The curve gets flatter as the reactant is used up.
• Measured concentrations (NCERT Example 3.1) (मापी गई सांद्रताएँ (NCERT उदाहरण 3.1)) — 0.100 mol L⁻¹ at 0 s down to 0.017 mol L⁻¹ at 800 s.
• Tangent at t = 600 s → instantaneous rate (t = 600 s पर स्पर्श रेखा → तात्क्षणिक वेग) — Slope = −5.12 × 10⁻⁵ mol L⁻¹ s⁻¹, so the rate at 600 s is 5.12 × 10⁻⁵ mol L⁻¹ s⁻¹.
• Two points read off the tangent (स्पर्श रेखा से पढ़े गए दो बिंदु) — (400 s, 0.037 mol L⁻¹) and (800 s, 0.0165 mol L⁻¹): slope = Δy/Δx.
• Axes: [C₄H₉Cl] in mol L⁻¹ vs time in s (अक्ष: [C₄H₉Cl] (mol L⁻¹) बनाम समय (s)) — Other instantaneous rates (NCERT): 1.22 × 10⁻⁴ at 250 s, 1.0 × 10⁻⁴ at 350 s, 6.4 × 10⁻⁵ mol L⁻¹ s⁻¹ at 450 s.
