Parts and what they mean

• log([R]₀/[R]) vs t is a straight line (log([R]₀/[R]) बनाम t सरल रेखा) — From k = (2.303/t) log([R]₀/[R]).
• Slope = k/2.303 (ढलान = k/2.303) — So k = 2.303 × slope.
• Line passes through the origin (रेखा मूल बिंदु से गुज़रती है) — At t = 0, [R] = [R]₀ and log 1 = 0.
• log([R]₀/[R]) vs time (log([R]₀/[R]) बनाम समय) — log uses base 10; ln = 2.303 log.
