Parts and what they mean
- [R] vs t is a straight line for zero order (शून्य कोटि के लिए [R] बनाम t सरल रेखा) — [R] = −kt + [R]₀: concentration falls by the same amount in every equal time interval.
- Slope = −k (ढलान = −k) — k = ([R]₀ − [R])/t. Unit of k for zero order: mol L⁻¹ s⁻¹.
- Intercept = [R]₀ (initial concentration) (अंतःखंड = [R]₀ (प्रारंभिक सांद्रता)) — Value of [R] at t = 0.
- Concentration of R vs time (R की सांद्रता बनाम समय) — Example: 2NH₃(g) → N₂(g) + 3H₂(g) on hot Pt at high pressure (1130 K) — the metal surface is saturated.
