(b) $\Delta T_f = iK_f.m$
(c) $\Delta T_b = iK_b.m$
(d) $\frac{P^0_{solvent} - P_{solution}}{P^0_{solvent}} = i\bigg \lgroup \frac{n}{N + n} \bigg \rgroup$

Answer 2

Activation energy ($E_a$) and rate constants (k₁ and k₂) of a chemical reaction at two different temperatures (T₁ and T₂) are related by :
(a) $ln \frac{k_2}{k_1} = - \frac{E_a}{R} \bigg \lgroup \frac{1}{T_1} - \frac{1}{T_2} \bigg \rgroup$
(b) $ln \frac{k_2}{k_1} = - \frac{E_a}{R} \bigg \lgroup \frac{1}{T_2} - \frac{1}{T_1} \bigg \rgroup$
(c) $ln \frac{k_2}{k_1} = - \frac{E_a}{R} \bigg \lgroup \frac{1}{T_2} + \frac{1}{T_1} \bigg \rgroup$
(d) $ln \frac{k_2}{k_1} = \frac{E_a}{R} \bigg \lgroup \frac{1}{T_1} - \frac{1}{T_2} \bigg \rgroup$
