Can rate law be negative
WebFeb 12, 2024 · In 1889, Svante Arrhenius proposed the Arrhenius equation from his direct observations of the plots of rate constants vs. temperatures: (6.2.3.4.1) k = A e − E a R T. The activation energy, E a, is the minimum energy molecules must possess in order to react to form a product. The slope of the Arrhenius plot can be used to find the activation ...

WebJan 14, 2015 · However, using this formula, the rate of disappearance cannot be negative. Δ [ A] will be negative, as [ A] will be lower at a later time, since it is being used up in the reaction. Then, [ A] final − [ A] initial will be negative. Therefore, the numerator in − Δ [ A] Δ t will be negative.

WebJul 19, 2024 · However, these powers can be fractional and even negative. For a complex reaction such as a A + b B c C the corresponding rate law can be written as rate = k [ A] i [ B] j Note that the powers i and j cannot be directly determined from the balanced chemical equation for a complex reaction. WebRate laws may exhibit fractional orders for some reactants, and negative reaction orders are sometimes observed when an increase in the concentration of one …
