Among the following graphs showing variation of rate constant with temperature (T) for a reaction, the one that exhibits Arrhenius behavior over the entire temperature range is a) / T ln k b) / T log k c) ln k /T d) both (b) and (c) . For a first order reaction A product with initial concentration x mol L − , has a half life period of . hours . For the same reaction with initial concentration x mol L the half life is XII U7 kinetics - Jerald XII U7 kinetics - Jerald - - - - a) hours b) hours c) .
hours d) Without knowing the rate constant, t / cannot be determined from the given data . For the reaction, 2NH N + 3H
