The rate constant and half life for reactions are related as ____(a) k α t0.5(b) k α (frac{1}{(t_{0.5})} )(c) k α e^(-t0.5)(d) k is independent of t0.5 |

Answer» Correct answer is (b) k α (frac{1}{(t_{0.5})} ) To elaborate: For 1^st order reaction, t0.5 = (frac{0.6931}{k}.) For all reactions of order other than 1, t0.5 = (frac{(0.5^{(1-n)}-1)×C_{A0}^{1-n}}{k(1-n)}. ) |
